Auto Tuning the HotEnd
Posted: Mon Dec 17, 2012 6:10 pm
I have everything completed....... I think.......
All motors respond to repetier fine.
I had to reverse the extruder motor in the firmware.
I have my Z height defined, and X,Y,and Z all moving to within .05mm of the table top. (How accurate do we need to be? I used an indicator in the pen holder.)
My hotend does heat up and Repetier monitors the temperature.
My heated bed warms up, the LED lights up, and Repetier monitors the temperature.
My Problem : As described on the wiki site, when Auto Tuning the hotend, I enter M303 S200 in the manual control tab, and get an error. "PID Autotune failed! Temperature too high. Error:checksum mismatch, Last Line:325 Resend:326"
This happens approx 3 mins into the process and Repetier shows the hotend at approx 221 degrees.
Please let me know if anyone has any ideas, fixes, sarcastic remarks, whatever you have that can get me past this last step!!!
Thanks........
