I received my A10 yesterday and already did some test prints... There seem to be a few issues, but overall its printing. One thing I noticed today, was that the preheat is very weird. Bed heats up fine to 50° and then the nozzle starts to go to 210°.
When it reaches the 210° it fluctuates between 206-218 and keeps jumping up and down... The status is still on heating and the print did not start at this point. After 30-50sec jumping around, it finally seems happy and starts printing, but the temp still varies during the print.
Today I also started noticing the extruder skipping steps. Not sure if that is related to the temp issue, but it sounds reasonable.
I hope some pro or geeetech support can help me out.
FW: Marlin 1.1.8
Filament: Geeetech PLA
Thanks a lot!
But unless you do some actual testing there's no way to tell if that's your issue or not. But the mean well power supply gives a nice piece of mind and if bought through places like amazon that offer warranties, you get a nice warranty with it.
Now as for my printer, the reason I had nozzle issues and the extruder skipping, one it needed the E-steps calibrated, which if you dont know is setting how much and how fast filament is getting extruded, if your trying to extrude to much the nozzle cant keep up and you will begin to skip. If your extruding to little you wont be getting enough filament extruded. Honestly a skip once every now and then is healthy it lets you know your printer is ahead of the game just a tad.
here is a link to a nice article from matter hackers on how to do e step calibration - here
Now the next problem I fixed, which probably has to do with a combination of filament (which was solutech pla ultra white), power supply and hot end. I would try to print at 220 and I kept having issues with extrusion and extruder skipping. My problem was even though my hot end reads 220 on screen its actually a nice 190. So I upped it to 240 and then beautiful printing began. Which I fixed this by getting a new power supply because my one hated my whole soul, and until I did I had to up my temps.
All printers will be off a bit on temps, so play with your temps a bit and see what temp works for you.
You can private message me if you have any questions I might be able to help.
Thanks, that really seemed to help. Temps are pretty stable now!vert wrote: ↑Sun Jan 13, 2019 5:11 pmhttp://marlinfw.org/docs/gcode/M303.html
hm, unfortunately the temp is still jumping around again between 207-214... i even saw a short spike to 204/219 once! that is definitely not normal :/
