Topic: Repetier Host not controlling 3d printer

Hello,
I uploaded the Repetier firmware to my Arduino Mega 2560 r3 board and connected to the printer with Repetier Host V0.90C.  However, when I go to the Manual tab in the software, the printer doesn't respond to any commands nor trying to move the device along any of the axis.  I know that the printer works because when I uploaded Sprinter, it works in Pronterface.  I am using the Com 7, just like Pronterface.  I really like Repetier Host.  Does anyone have any suggestions on how to get the printer to respond?  neutral


Thank you.

Re: Repetier Host not controlling 3d printer

Are you sure you changed the Configuration.h file for the correct board you have?

Re: Repetier Host not controlling 3d printer

Does RH show any errors?

Re: Repetier Host not controlling 3d printer

Sorry it took so long to reply.  I set the configuration.h file for the Arduino Mega 2560 which is Motherboard 33.  Repetier Host connects to the printer.  At the bottom of the RH screen it says "7 Command Waiting".  What does this mean?  I presumed that I could go to the Manual Tab and move the motors.

Re: Repetier Host not controlling 3d printer

There are some pin differences between Marlin and Repetier firmwares.  I 'm not by my printer at this point but check the pins.h file.  I think the #define X, Y + Z max_pin's in pins.h should all be set to -1 and dfine SDSS should be 25 for Ramps/Arduino mega boards

Where is the define SDSS statement?

Re: Repetier Host not controlling 3d printer

I had to turn off the (new?) reset on connect printer settings to get past anything but commands waiting.

Re: Repetier Host not controlling 3d printer

Define SDSS is on line 341 in the pins.h

Re: Repetier Host not controlling 3d printer

O.K.  So after working on this all day with some expert programmers, we are all still stumped.  I am using a Ramps 1.4 board on an Arduino Mega 2560 r3 board.  The 3d printer is a Prusa Mendel I3. 

Sprinter works fine with Pronterface, but no LCD capability.

I tried Repetier with Repetier Host, but the motors don't respond. 
Next, I tried Marlin v1 with Repetier and Pronterface.  Same thing - motors not working.  I get an error message in Pronterface:  : Extruder switched off. MAXTEMP triggered !
Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

I get the Repetier Host error:  Error: checksum mismatch, Last Line: 3 and so on.

Any suggestions??

Re: Repetier Host not controlling 3d printer

Check your thermistor.. Make sure it's connected properly, not sorted, and reading temp (assuming you can still connect).

Trying homing RH if you are able to get it to connect.

Re: Repetier Host not controlling 3d printer

Whenever I connect using sprinter and Prontra face everything works perfect. However whenever I upload Marlin as the firmware it won't work with Prontorface or RH. This suggests to me that it is in the Marlin firmware settings. I have set the configuration.h file for motherboard 33.  I believe the problem lies within the pins.h file. That would explain any thermistor errors or motor control errors. For the time being sprinter works fine with Prontorface. However I don't get the benefit of using an LCD reader.

Re: Repetier Host not controlling 3d printer

Did you get anywhere with this issue? I have the same. Communications is working and and Repetier will drive the all the motors correctly to their Home position and respond to the end stop switched-, but no control is coming form the manual controller. Very strange....Im using Arduino Mega 2560/ Ramps 1.4/ Repetier 1.0.6 and marlin firmware-

Are you getting any errors in RH such as max temp or cold extrusion prevented?

Re: Repetier Host not controlling 3d printer

Try using this version of Marlin. It is preconfigured for a Da vinci 1.0 and RAMPS 1.4 with LCD but should get you in the ball park.

I'm just gonna throw something here different ...

    How about your Printer PORT settings ?

Re: Repetier Host not controlling 3d printer

Was having this issue:

Make sure the baud rates are set the same in "configuration.h" and the "printer settings" in Repetier.

You guys have probably solved it already however smile
