Hello all. I am new here and have never done anything of this nature before. I have done my best to follow all the guides provided as well as searching for similar issues in the forums. I am having several problems.
1: When I push home in repetier my MPCNC will move until it hits the edge and grind on the belt till I hit E-stop.
2: I can’t seem to figure out how to set the max travel distances on my MPCNC. I currently have no limiter switches.
3: I am having a temp error that claims I must reset with M999. I bought the ramps from Vicious and have placed the small resistor on 11.
4: Currently the only movement I able to achieve is by clicking the home button in repetier.
My questions:
1: How do I set the mins and maxs on the MPCNC without limit switches?
2: How do fix the temp error?
3: How do I get more movement such as using the buttons to move 0.1mm, 1mm, 10mm…?
Thank you in advance and merry christmas/happy new year.
Also If I am violating any sort of forum rules please inform me. This is the first time I have ever posted in forum and would like to make sure I am following the rules.
If you have no limit switches, you can’t use home, limit switches tell it when it’s ‘home.’ I use limit switches to square the long axis of my big machine, but I don’t recommend starting with them. You likely don’t need them yet. Just keep your projects sized under your cutting area.
To define a home, you can hit the reset button on your RAMPS set, or type G92 X0 Y0 Z0 in your terminal when the carriage is where you call home. To make Repetier read out correctly, you can also type @isathome at that time to reset Repetiers meaningless coordinates. I’ve made one of rep’s five script buttons to set home coordinates, I use it a lot.
You might have your resistor hooked up to the wrong spot, or maybe it got pulled out after your initial moves. Double check it and issue the M999 to reset. Good Luck!
I am guessing you didn’t buy it from me. I test all my boards, for this to happen it seems like you have a thermistor pin short. You might want to check the underside of your ramps shield for anything obviously shorted on that pin.
In the firmware, under the configuration.h tab, there is a setting that says
I could have possibly screwed it up. When I initially received the bundle I was unaware that the firm where was already on the board so i attempted to upload it. I must have messed something up then. I will re-upload it and try again. Thank you for all your help .
How do you do a tool change using ESTLCAM and Repetier? I know I can select a two different tools in ESTLCAM but can’t figure out how to restart repetier once it pauses for the tool change.
