Re: EZStruder stops feeding on retraction

Teeth marks are normal and to be expected. What would be a problem is if the gear ground partially through the filament far enough to slip. Do you hear "popping" noises when the extruder is trying to feed the filament but can't? That's a sign of a slipping extruder. I got rid of my EZStrud...

Re: Temp Undefined, possible broken heater for HE280

NP. Next we need to look at your thermistors. But since both were going astray, I suspected a voltage drop problem. And I'm still confused from your original post stating: "I tried the voltage across the fuse on the heater and the voltage going across while on is >12." Could you post a pic...

Re: Problem getting extruder to run

Just out of curiosity, what is your hotend temp when you try to extrude? If it's too low then the extruder won't run.

The next thing to try is to unplug one of your axis steppers (X, Y, or Z) and plug your extruder stepper into it. Now does it run when you do a move?

Re: EZStruder stops feeding on retraction

Well, if the knob is still moving it's not the stepper motor... Take a close look and see if your drive gear is slipping on the EZStruder's shaft. Let it run for several minutes and pull out the filament. Has it been ground down where it meets the drive gear? Do you have a bunch of filament grinding...

So many questions... :) "I see on the side of the heater there is a 115 and a 230, should I push it so that the 230 is available?" Unless you live in an area where the voltage is 230 volts (Europe comes to mind), then no. That's to select your input voltage for your power supply, if you li...

Well yeah, if you have it off while you measure for voltage, it would be a display of a fundamental lack of electrical understanding. And since one of the things that he is looking for is voltage drop, he's going to need volts and a load. And since he's getting some heat, it's obvious that the fuse ...

Re: Rostock Max v3 Stops Moving after a while

Pretty much, but it really isn't missing anything that you need to run a 3D printer. The stepper drivers have a lower current limit, but still well above what your steppers would normally draw. It supports two extruders and a dual Z. And it's ~$120 as opposed to ~$180.

Re: Temp Undefined, possible broken heater for HE280

I'm with Gene on this one, I'm going to say that you have a loose connection somewhere. First off, the voltage check that you did on your your heater indicates a blown fuse. The classic way of testing for a blown fuse is to put a voltmeter across the fuse. If it shows voltage, in this case 12 volts,...

Re: Stepper motors just stopped working?

Hmmm, I think that it's something in the firmware, which would explain why a fresh install of Octopi wouldn't fix it. What controller does the V3 use, and what firmware (and version) are you running?

Re: Orion Prints not coming out square

No problem! For me, replacing the effector platform helped quite a bit.

I hate to say it, but my Tronxy A8 clone beats the pants off of my Rostock when it comes to build accuracy.

Edit: By the way, check your belts for tightness. I can see where that would cause mushy corners.

Loose hob gear on the extruder? Although I would expect to see it get worse at higher speeds if that was the issue. But, I'd check it anyways.
