Hello,
I use Arduino Mega 2560 and Ramps 1.4
I use Repetier-Firmware configuration tool to set firmware on my DIY-SLS-3D printer. It works well with motor control but when it comes to laser:
I have no voltage output on D10 while I use G1/G2/G3 code, so setting laser power has no influence
I use:
G452 //set firmware to laser mode
M3 S150 //set laser power for example to 150
G1 X100 //it only moves to X100 but laser dont work while this.

Can anyone help me?
Also here is URL for the project I've followed

slicing problem with Cura for dual extruder

Hi,

After modifying my prusa i3 with the Cyclops dual extruder, and configuring the Repetier firmware, I made my first tests

-Slicing with Slic3r an printing with one color is OK

-Slicing with Slic3r an printing with two color is OK, but dirty so I need wipe towers.

I decided to test Curaengine as I heard it did a great job for the wipe towers.

I configured it as I guess it should be but the slicing gives a weird result, like if the two colors are getting wiped on every layer.

The other problem, if I launch the printing process is that the nozzle heats too much (220° instead of the 180° configured)

Here's a capture of the slicing, I expected to see the same colour in the tower and not alternate colour on each layer

Here's my configuration, if it can help:

Print queue not working?

I just updated to 0.93.0 and my print queue is acting a little different.

If I have something printing and I send another file to the print queue it works as expected. However if I have a file in the queue and nothing printing, sending an additional file to the queue results in that file being printed immediately.

Not sure if this is a bug or intended or simply a new setting I’m missing.

Power Loss

Hello,

in case of Power Loss, is it possible to save the state of the print and start over from that point?
I did not find any topic on this.

I do not print from SD and Marlin or other solutions are always from a print initiated from the sd card.
I use software to manage the printer so I would like to have the option to save the state of the print and in case of power loss, to recover the print from the point it stopped.

Possible?
Thx

The expected time to finish the print is the same time to notification. I print a model upload in a Repetier Host and sliced with a Slicer software (see attached image). 
Can you give me some indication to correct it?

User preferred date/time format in UI

Hi there,

Request
Possibility to select what date/format is used UI. Either at user-level or server-level. 

I know that date/time-format in Repetier-Server follow the selected language. However, I still prefer English (even if my native language was an option), but it's quite annoying that date/time format is forced to US-based when using english.

The question/request as been asked before:

I belive that other than me / non-native-english people, still prefer english, but also wish to select there localized date/time format.

Would you please consider this again?

Thanks in advance :)

Best regards
Dan

Repetier (Firmware + Host) + Ramps + alternative Serial adapter

March 19, 2018, 4:07 pm

Hello,
I'm working on a serial TFT as addon for my printer.
I'm using a STM32F01xxx as MCU, so my configuration is:
Repetier Host <-> STM32 <-> Ramps 1.4
I wrote a simple pass through code for the STM32 , so every incoming message from repetier host is directly send to ramps 1.4 and vice versa. Everything is working fine (like local echo, sending Gcodes), but Repetier Host wont get any connection, so I think, I'm missing something:
Normally via USB connected RAMPS will start a reset sequence when Repetier host is connected - but it doesn't do that in my scenario.
More details:
The alternative Serial (STM32) is connected via D0 / D1 (serial 0 = USB serial), I know this might be a problem because of an USB-serial conflict. The ramps board is NOT connected via USB. There are no problems with baudrate or different voltage levels (added a level converter, normally there is no problem using 3.3v and 5v, but I even checked this), neither with my STM32 code (serial passthrough is a easy going thing).
So are there special start codes (didn't sniffed them on my serial monitor) with repetier host or need I change some firmware settings bypassing serial USB on ramps? Oddly enough Printrun as host is working flawlessly - only repetier host refused to work with my setup.
I believe Repetier Host is using the DTR/CTS pins for the start sequence?
Has somebody any hint?

thanks Matthias

Version 2 Compilation Errors

December 28, 2019, 12:06 am

I'm following the instructions from https://docfirmwarev2.repetier.com/ and trying to compile firmware version 2 (the very 1st time). I am getting errors that are most likely caused by incorrect settings in my Configuration file. I'd appreciate any help/guidance.

My IDEX printer has two X motors, one Y motor, two Z motors and 2 extruder motors. So, 7 motors in total. Each motor is connected to its own driver on Ultratronics Pro board. 'Dual X Axis Printer' configuration sample published here https://docfirmwarev2.repetier.com/config/printer_type/ contains the following
#define NUM_AXES 5                   // X,Y,Z and E for extruder A,B,C would be 5,6,7
Why this example contains 5 axes? Dual X printer should have at least two X, one Y, one Z and 2 extruder motors. So, the number should be 6 or higher. If not, than what is the meaning of AXES in this context?

Other 2 settings that are puzzling me are
#define MOTORS \
    { &XMotor, &YMotor, &ZMotor, &AL1Motor, &AL2Motor }
    
#define MOTOR_NAMES \
    { PSTR("X"), PSTR("Y"), PSTR("Z"), PSTR("Adj. 1"), PSTR("Adj. 2") }
I tried to replace the last 2 entries in each of these lines with with A, B, C and D, but getting several errors like this:
src\motion/MotionLevel3.h:113:9: error: 'AMotor' was not declared in this scope

Prior to this I was getting several Servo related errors, nevertheless I defined NUM_SERVOS as 0. 

Here are couple of them:

src/Configuration_io.h: In constructor 'Servo1Class::Servo1Class()':
src\io/io_servos.h:36:18: error: 'servoMicroseconds' is not a member of 'HAL'
             HAL::servoMicroseconds(slot, neutral, 1000); \
                  ^
src/Configuration_io.h:179:1: note: in expansion of macro 'SERVO_ANALOG'
 SERVO_ANALOG(Servo1, 0, Servo1Pin, 500, 2500, 1050)
 ^~~~~~~~~~~~

I was able to get rid of these errors by commenting out the line 

// SERVO_ANALOG(Servo1, 0, Servo1Pin, 500, 2500, 1050)
from Configuration_io.h file, but I don't know if this is good workaround.

Thanks

Start both heaters at once (and where is the phantom start code coming from?)

I have an Ender 3 and the PSU can easily run both heaters at startuip so I want it to do that.
In Printer Settings, I can see sections for Start GCODE, End GCODE etc. They are all empty.
And in the Slic3r settings -> Printer settings, I can also see sections for Start G-code, End G-Code etc. These are NOT empty.
Howver, neither of these contain the code I see at the start of all my GCODE files prepared by Slic3r on Repetiere Host, which I've included below. As you can see, it does two "turn on heater and wait for temp" commands, one for the bed and one for the nozzle.

So - where is that code coming from and how can I change/remove it from my sliced files?

Thanks

Hi,
I've searched everywhere without success.
I've just installed the last Repetier Server on Raspberry Pi, linked via Serial at bigtreetech skr 1.3.
After the configuration, the touchscreen (kuman SPI 3.5") works correctly, but doesn't show "move" menu, "Temp. Graph" menu, "Extruders" menu.
Don't find any solution.
Have any ideas?
Thanks.

Hi there, I've just set up a Prusa I3 Pro C and using Repetier Host without the Server. I've started my first job and Repetier Host is saying "Heating Extruder" but the extruder isn't heating. How do I work out what is going wrong? What things should I check? Repetier is saying that it is connected to the Printer. Any advice would be appreciated.

Hello,

i am using the Repetier Server Monitor with the Upload Feature.

When Repetier Server Monitor creates the Upload Directory it use the "slug" tag.

Is there any way to rename the internal slug tag?

currently my printer name looks like this and its a little bit confusing for uploading new files if you have more printers on a server.

<name>Prusa i3 MK3s MMU2s</name>
<slug>Prusa_i3_MK3s3</slug>

Good Friday! I bought the server and I am loving all the features where I can attach multiple printers to a Raspberry Pi 4.  I have 2 Prusa Bears currently in my growing print farm and I would like to be able to see my bed level (i.e. like Pusa Mesh Map) so that I can adjust my level manually via a mod I did to my bear with the nylon lock washers.  

Does Repetier have an add-on that can help me?

Main screen missing durring print

When I am printing from SD the main screen (the screen with 4 different groups) in no longer an available screen to view. When I turn the encoder the other screen will show up (printing time, location, temps), but the main screen is gone. It appears that the "status screen" that only shows the percentage done takes the place of the main screen. Is this normal?

Here is the screen I am talking about that is missing while printing. https://i.imgur.com/r8QybP4.jpg

Screen Changes since 0.92

Hi,

just managed to update to the 1.04 Version. Using a RepRap  12864 Grafics Display, I noticed some changes, but I don't know if these changes are due to the new version or something I have done within the very first steps of fiddling with repetier.

New: During print, I have a progress bar now. I can change a few values, so it's ok... (for now).

Old: There was the four-quarter view as it was during no-print times. Via quicksettings, I could change the same values as it is possible now. I could also enter the configuration during print to change acceleration values or write them even to eeprom. This is gone now.

Any way to get it back? (Well besides of going back to old version, to avoid the most obviuos answer :-)

Firmware upgrade from version 1.x to 2.x. User experience.

December 30, 2019, 11:12 pm

Back in October I volunteered to participate in Repetier firmware version 2 testing and the last weekend I finally started upgrading my printer’s firmware from dev. version 1 to version 2. In the following series of posts I will share my experience. Hopefully, this will save other users time and help developers to understand end-user’s experience and how to improve it.

 I consider myself being advanced user. I have years of software developing experience, worked in the field of designing electronic boards and PCBs. I bought my first 3d printer almost 4 years ago, which I run on Marlin, Clipper and later on 0.9x and 1.x versions of Repetier firmware. If you are new to any of these areas, your experience may be different, but the good thing is – Repetier developers and other members of these forums are extremely helpful and I never had a case when my question here left unanswered. So, if you got a question – just post it here.

Now about my test environment. After countless upgrades done to my first 3d-printer Velleman Vertex K8400, I reached the point when I was ready to build my own 3d printer from scratch. I decided to go big with IDEX (Independent Dual EXtrusion) design that has 2 print-heads moving independently along X-axis. I may publish the photos later, once the printer is complete, but for now here are the specs of the printer that I am upgrading:

Specifications:

Kinematics:  Cartesian
Mainboard: Ultratronics Pro 1.0 with 32bit CPU
Number of steppers: 7 (2-X, 1-Y, 2-Z, 2-Ext. Z-motors are working in sync, but each has own stepper driver)
Number of steppers drivers: 7  (4 - TMC2100 - E0, E1, E2(Z2), Z,    3 - DRV8825 -  X, Y, E3(A) ) . Will be upgraded later.
Number of hot-ends: 2 (e3d-v6)
Number of fans:  4 (2 - filament, 2 - e3d-s)
Additional fans: 2 (1- mainboard fan directly connected to +12V, 1- Raspberry PI CPU fan PWM-controlled by RPI via custom extension PCB)
Print bed: 40x40cm heated by 110V AC. Moves along Z with Z-Max at the bottom.
Print surface: 3mm borosilicate glass
Network access: via Raspberry PI 3B+ (RPI) and Octoprint
Solid State Relays (SSR): 2 (one for mainboard power supply, controlled by RPI, another for heated bed). Control voltage 3V-32V DC.
End-stops: 4 - Optical,  custom PCB based, use ITR9606-F sensor (schematically similar to Vertex K8400 end-stops)
Z-probe: 1 - Optical with a pin touching the bed (my own design), the sensor is the same as in end-stops. Attached to the right side of left printhead. Activated/deactivated by rear-earth magnets when printhead moves to specific X,Y coordinates.
Servos: None
Thermocouples: None
Filament jam sensors: None
Filament sensors: None
LCD: None (to be added later)
Mainboard power supply: 12V 
Additional power supplies: 2 (RPI power supply and 5V DC supply for controlling main power supply’s SSR

Mainboard connections (plug – connects to):

XMOT – X-motor (Left print-head)
YMOT – Y-motor
ZMOT – Z1-motor
ZMOT1 – Not used
E0MOT – Left Extruder-motor
E1MOT – Right Extruder-motor
E2MOT – Z2-motor
E3MOT – A-Motor (Right print-head)
E0 – Left print-head heater
E1 – Right print-head heater
E2 – Left print-head e3d fan
E3 – Right print-head e3d fan
HB – Heat bed SSR
HBIN – 12V from main power supply
Fan1 - Left print-head filament fan
Fan2 - Right print-head filament fan
T0 - Left print-head e3d thermistor

X+ – X-stop at the right end of X-axis activated by right print-head
Y- – Not used
Y+ – Y-stop at the rear end of the printer activated by X1/X2 gantry
Z- – Z-probe sensor
Z+ – Connected to one of 3 Z-max sensors installed at heights 150mm, 300mm and 450mm. Sensor/height selection is done by electronic switch on custom PCB controlled by RPI. For these tests Zmax=150mm was used.
USBP (Programming port) – Connected to RPI, or to PC when firmware update is required.
USB (Native port) – Not used (never worked by some reason)
Ethernet port – Not used
TC1-TC4 - Not used

To be continued…
