Motors not responding to all manual controls

Software / Firmware
1

I have completed my build, and am now at the point of testing out the electronics / steppers. I am just attempting to get the machine moving and will eventually use it as a CNC router, and do not currently have plans to use it as a 3D printer.

All the stepper motors are wired up correctly as far as I can tell. When i open up Repetier-host, and attempt to use the manual controls from the “Print Panel”, I am able to successfully send the X, Y and Z to “home” by pressing the home button for each axis. However, when i attempt the to do incremental steps (0.1, 1, 10, 100) nothing happens and I get this error in the console log:

< 12:32:19 PM: Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

Here is my log when Repetier-host initially connects. NOTE at the end there is a temperature error here as well:

I have tried the same thing in Pronterface and Simplify3D, and all give me the same errors. I have also tried on windows and mac with same result, so i assume it is a configuration i am unaware of, but i am not sure if it is a Marlin firmware config, or a setting in Repetier-host or something else. I am also not sure if I was supposed to hook up the resistor on the RAMPS board that came in the kit, even though i am not intending to do 3D printing?

I purchased the hardware/electronics kit from this site, and printed my own parts. The kit was purchased about 2 weeks ago.

Any assistance is greatly appreciated! This is my first CNC build, and am new to the software and firmware.

Hi,

I’m still in the process of building the mpcnc myself but I guess it is the missing resistor on the T0.

See link to other post

Yup you need the resistor on pins t0, repetier should then show a temp of about 25C when you connect.

Yep, that was the problem! I guess i misunderstood, and thought i only needed to hook that up if I was using it for 3D printing. Manual controls work great now.

Also, just as a matter of documentation, i saw some posts where people had problems communicating with the board on a Mac. I edited the configuration.h in the firmware, and changed
#define BAUDRATE 250000

to be

#define BAUDRATE 115200

and now i can connect to the board no problem.

Thanks again for the quick response Bert.

Good tip thanks, I don’t have a mac to test with so that helps.

Yeah, one other thing I had to do to get Arduino IDE and Repetier to connect on my Mac running El Capitan OS was install the drivers for the Chinese Mega. I got the driver and instructions from this site: http://kiguino.moos.io/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html. Installing that driver, along with changing the baudrate in the firmware seemed to do the trick. I’ll update as i progress if there is anything else i find.

Great design BTW…cant wait to start my first cuts…
