Unresolved Software problem ...

I was attempting to print a part yesterday. It would get so far then it sounded like the machines servos were having trouble as it was happening on corners only. The machines do not have circular interpolation so it finally dawned on me later in the day after I had given up. The program was full of small moves which was causing the machine to catch up to the Cura software as it was calculating the moves I assumed (Which may be incorrect but the solution shows this is perhaps the reason). I changed to Simplify 3D, which creates the entire file before printing, and the problem went away. Just something to consider if you should fall into the same problem.

 

Uh all software generates the entire gcode before printing. Might have been a usb comm issue

 

That would be a RTS and CTS signal not being monitored correctly.

 

Wonder if that could be my issue, what corners were effected, all or just on one side.

 

It slowed on all corners but those on the right upper corner started first for some reason. As it went on, they all got horrible and would skip over sections of the corner. The communications error sounds possible as not monitoring the RTS and CTS signals will cause data overflow. That would make sense because most giveup and go the the card reader which is internally controlled for software flow.

 

I wish I could send to card from Cura to test, as I really need the brim setting, I hate rafts. on Simplyfy3D site debating to hit the buy button.

 

You have to get the Autolevel fix that is on this forum for Simplyfy3D. It take some figuring out but I finally sat down and took the time to understand everything in the software after the problem yesterday. I will not say it will fix your problem but it made mine go away.

 

I am testing using the sd card from mattercontrol to see if that helps. Thanks

 

Slice in cura, use repetier or MC for sending to SD
