I finally installed and started to run an orginal kickstarter Maslow. I followed the calibration procedure and everything looked great. I started some test patterns and a dialog box went missing in-between cuts.
I shut Ground Control down (v1.26), opened the G-code file and tried to start again.
I received a notification “Unable to find valid machine position for chain lengths xxx, xxx. please set the chains to a known length. Action - set chain lengths.”
I tried to re-run the automatic calibration procedure and almost destroyed one of my pulley systems, which started a motor overload warning. I power cycled the maslow and restarted the program because the motors wouldn’t turn happen after the alarm.
I ran through the automatic chain calibration procedure again with no problems, marked the chains, got everything connected, tried to run the pattern again. I received the “Unable to find valid machine position for chain lengths xxx, xxx. please set the chains to a known length. Action - set chain lengths.” again
I cycled power and restarted the program. Same thing.
I found this post “How To: Manually Reset Chains, the Easy Way” and followed the steps several different times. Same message again.
I deleted the grouncontrol.ini file and restarted Ground Control and power cycled the Malsow. Now I get the chain error almost immediately after starting gorund control.
I opened Arduino and resent the firmware, restarted Ground Control and power cycled the Malsow. Same error. I notice that I am getting the following errors
- G21 Connection Timed Out. It is possible that the serial port selected is not the one used by the maslow’s Arduino, or that the firmware is not loaded on the Arduino.
*PCB V1.00 Detected
- error: EEPROM fail. Using default settings. Grbl v1.00.
I tried resetting the eeprom through ground control. Then I tried Reset settings to defaults in Ground control.
These are the messages I get on ground control startup.
Ground Control 1.26
Firmware Version 1.26
I noticed that Arduino recommended updating my board to 1.82, so I did that and then uploaded the Maslow firmware again.
I gave up on ground control and went to webcontrol.
Everything looks good when I open it and start setting it up. All green on the top and a green alarm cleared menu.
None of the buttons in the set sprocket menu work. Testing the encoders gave no results.
I went back to ground control and tried testing the motors and everything failed and I got the same message again.
I’ve run out of ideas. Any help would be appreciated.
