Topic: help with the clear petg causing the motor to bog

Got my filastruder set up and started running the ABS through it and it did about half of it fine then I had a family issue and had to basically pull the plug and run. I came back heated it up to 180 and let it sit for 30 min before trying to extrude. When i flipped the motor switch it torqued a bit over and then it then went into stall protection at 1.6 amps. (ended up having to dig the plastic out of the barrel. Once that was doni finished the e I was able to get it to extrude and it would go fine for 10-15 feet worth of filament but then would jamb up and overcurrent.
Now I have 12 lbs of the Clear Petg and I am having the same problem with it. I have tried temps from 180 up to 230 but no mater what I try it stalls out. I even moved the stall current up to 2.0 and same thing (dont want to twist or bend the pipe) I have searched through the forums and tried most of the things others have tried except for drilling out the nozzle. If i load the filament a little bit at a time it extrudes fine but If I put anything in the hopper (20 oz. coke bottle) even just 1 inch into it, it will extrude for a bit then jamb up. Is there anything I can try to get this to extrude without bogging down and having to dig out the filament from the nozzle again?
I checked and lubed the thrust bearing, finally got the auger shaft straight in housing with the gearbox output shaft from a earlier post, and I have the proper 2 mm of clearance with the drive socket internally.

Any help is appreciated I look forward to participating in this forum.

P.S. this is the EASTAR Copolyester 6763

Can you post pictures of your setup?

I originally had issues with the screw not lining up inside the filastruder but I was able to get that sorted and it turned fine as long as I don't have the hopper full. empty it pulls .5 amps and when it is extruding good it pulls 1.5 to 1.7 amps but after a little while it will bog down and seize up it seems like. If I leave everything on every 10 to 15 seconds I could hear it free up for a second but goes right back to seized up. If I dump the hopper and let it go then after it sets for 10-15 minuits it will start extruding again. and it will be fine as long as I don't load up the barrel again. It almost seems like it is getting to much head pressure.
Sorry for the delayed response I managed to break my vertical hopper and dump about a half pound of clear petg pellets everywhere ????. Wife is pissed ????. should have new hopper on it today and will post a video of it tomorrow morning. 2 Questions though. The Vc pot and the Cc pot. I know the CC pot limits current to motor. What exactly does the VC pot do? I imagine it controles voltage output correct? Other question is what can I safely take the stall current up to before I risk bending the barrel? currently at 2 amps and It has helped alot but don't want to damage it before I can design a new welded barrel setup for it.

Beyond 2 amps risks bending the barrel, beyond 2.4 amps risks accelerated wear to the gearbox.

CV limits voltage, yes.

Re: help with the clear petg causing the motor to bog

Thank you Elmore, I did read through that post already. Quick question Is the barrel just a standard 1/2" black iron pipe? looking at possible building a spare barrel and welding a hopper together with the barrel for strength. just playing with ideas on it really. I ordered some new nozzles for it also since I accidently drilled my nozzle out to much. (got the 1.8 and the 2.3 bits mixed up.)
