![]() You might try replacing your long M227 lines in the scripts with ONLY "M227 S100" and see what that does for you. This creates the horrible jams we've all experienced. When the heat migrates up into the extruder, the filament softens and starts wrapping itself around the idler pulley. In any case, it looks like the P parameter is causing too much back-pressure in the hot-end and causing extruder skips. (I'm guessing the G and F are speed/accel related extruder params, but haven't confirmed this). The S seems to be the retraction, but it also advances the same amount. I believe the P parameter may be the "extra restart distance". It is still de-stringing very nicely, but the extruder doesn't skip at all. I'm running prints now with PETG and using only M227 S100 in place of the M227 PXXX SXXX GXXX FXXX. I do believe the problem is made worse by the chamber temp, but the true cause seems to be the M227 PXXX parameter. I've been experimenting with the M227 parameters a bit and think i've stumbled upon something that was causing my filament errors. I will go on with tests and give you the parameters if some of them change by the future. The nozzle temperature was 195☌, written in the changing tool Gcode. But for the mixed material building, after a few tests, I obtain good results by setting the heating chamber parameter to 40☌. I tried to extrude PLA without heating the chamber and the printing achieved correctly. ![]() I think its made worse by the fact my PLA is quite old now so may have deteriorated.īTW, I use the default settings of 0.35 dia, 0.90 multiplier, 0.40 width and get good results at 34mm/s. Its by no means scientific but I only ever turn the heater on when doing pure ABS prints now. I ran it again without heating the chamber and it built fine. Only last week I did a mixed build where I heated the chamber and twice had the PLA jam. If you are doing a mixed material build with ABS and PLA, I find its best not to heat the chamber at all. I run the PLA at 210 for first layer then 200. In my experience there are a few things that can make this happen though.

I can't remember, but it seems to me that if i didn't enable it in software, the M227/M228 commands didn't seem to work either. I haven't done too much experimentation with how these relate to Simplify's retraction code, but it seems to work enabling retraction but making the retraction a very small amount in software. I would copy the M227/M228 lines from the CUBEPRO software's output and paste them into your profile. I dont completely understand the M227/M228 commands, and there are a TON of conflicting posts on other forums about them-most of them pertain to the Cubex, which didn't seem to have as many parameters associated with them. I've narrowed my problems down to the retraction settings. Does anyone has good result with PLA? Which parameters should I use to solve my issue? So, I think that my extrusion parameters are not adapted to the PLA. Several times I had to disassemble the motor and the extrusion system to clear the clog. With the Cubepro software, there is no problem, but with S3D after 5 or 6 mm, the printing stops with the error code F22. But for few days, I have tried to extrude PLA to create support. Like I said in my last messages, I can extude ABS without issue. Mix and match colors.I've a new problem with my cubepro profile. Prints in three materials: Nylon, ABS and PLA plastic.Controlled print environment for high quality, precise prints. ![]()
