Hi again. I downloaded and installed 062. I had the same issue. A quick question though. Is it OK if I use the xml file from the newer version?

I think the problem happens when I go to the the toolpath tab. If I do not go to the toolpath tab it seems to be OK.

I am going to try 057 as soon as I get a chance and I will let you know. I am sorry this is taking so long but I have many projects happening right now. Thanks again.

So everything homes ok when you are on the main page?

At some point something happens that causes the homing sequence to stop and the only way I have found to recover is to replace the xml file with one that was backed up when the homing sequence worked.

Some additional troubleshooting steps I have tried. Disabled and then re-enabled the home switches disabled shut down then re-enabled, disabled shut down rebooted then re-enabled. Reinitialized the usb breakout board. No luck

I have not had a chance to verify this yet but it seems that after I have gone to the toolpath tab, run the road runner gcode a few times, this problem occurs (by the way I have made a few beautiful road runners). If I go back to the main page and the problem exists. I hit ref all home and the leds flash red then green the dros do not change and the axis do not move. If I go to the diagnostics page none of the home switches are active. If I try to home each axis individually I get the same result, the home led flashes and nothing else happens.

Next time this happens I will save the 'defective' xml file and then try to compare it to the working file to see if there is some difference.

I am now on ver 057 and the same problem. I have saved the bad xml and compared with the good xml and there are a few differences. I have no encoders so I am thinking that a value other than 0 for the <enc> and <encoder> tags in the bad xml file is causing the issue. I will set those values back to zero this evening and see if the bad xml works OK.

Bad xml
<Dist0>7.2e+002</Dist0>
<Dist1>4.6e+002</Dist1>
<Dist2>1.2e+002</Dist2>
<Enc0>-10.</Enc0>
<Enc1>-5.</Enc1>
<Enc2>-1.</Enc2>
<Enc3>0.</Enc3>
<Encoder0>-10</Encoder0>
<Encoder1>-5</Encoder1>
<Encoder2>-1</Encoder2>
<Encoder3>0</Encoder3>
<Encoder4>0</Encoder4>
<Encoder5>0</Encoder5>
<Encoder6>0</Encoder6>

Good xml
<Dist0>6.1e+002</Dist0>
<Dist1>3.9e+002</Dist1>
<Dist2>1.e+002</Dist2>
<Enc0>0.</Enc0>
<Enc1>0.</Enc1>
<Enc2>0.</Enc2>
<Enc3>0.</Enc3>
<Encoder0>0</Encoder0>
<Encoder1>0</Encoder1>
<Encoder2>0</Encoder2>
<Encoder3>0</Encoder3>
<Encoder4>0</Encoder4>
<Encoder5>0</Encoder5>
<Encoder6>0</Encoder6>

Setting those vales to 0 made the bad xml good. So the question is where and how are those encoder tags getting changed?

Can anyone check and see if there is a problem with the xml file hat could be causing my issue?
