Re: max speed of M2

what is the max speed that the machine will try and print There's a limit in Configuration.h : https://github.com/MarlinFirmware/Marlin/blob/1.1.x/Marlin/Configuration.h #define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 } Multiply the X and Y values by 60 to get mm/min, as used in G-Code: 30000 mm/min...

Is their a fuse somewhere that I need to change?
The firmware won't drive the motor unless the hot end is at the proper temperature.

Check that first …

Re: Z axis problem. Is this a problem with the motor or the driver?

Any analysis of the data from my previous posts? You've been doing a lot of fiddling with the machinery as part of finding the extruder problem, so: did you, at any time, even once , unplug / disconnect the Z axis motor when the power was turned on? If so, that likely killed a driver transistor in ...

Re: Z axis problem. Is this a problem with the motor or the driver?

I took the bottom of the motor apart No sugarcoating: disassembling a stepper demagnetizes the rotor. You must buy a new Z-axis motor. The motor is assembled with the rotor demagnetized, then it's magnetized in place. When you take it apart, the rotor smacks into the stator, which creates a localiz...

Re: Z axis problem. Is this a problem with the motor or the driver?

the technical reason why the motor would move in the opposite direction The windings set up a rotating magnetic field which, in normal operation, drags the rotor around with it. When the rotor stalls, it vibrates back-and-forth and may wind up synchronizing with the field in the wrong direction. Ol...

Re: Z axis problem. Is this a problem with the motor or the driver?

the random up and down movement doesnt make any sense It's what happens when a stepper is mechanically overloaded: the rotor can't turn at the commanded rate. Start by cleaning & lubing the Z axis guide rods and leadscrew. If that solves the problem, just clean and lube a bit more often. Which none...

the filament is randomly going in the filament drive slightly bent
Is the filament guide tube installed?

None of your pictures show it and, without the tube, the filament will kink as it feeds.

Re: burned(?) PETG in prints

just using them as they were The guy who gave me the idea made a positive duplicate of the nozzle, created a negative mold of a boot surrounding it, then cast silicone rubber into the mold to make the boot. I liked the silicone boot idea, but all the mold-making & casting seemed like way too much w...

Re: burned(?) PETG in prints

What do you think is causing this? The other end of each fine hair you see on your PETG objects melts back onto the nozzle, accumulates into an oxidized blob, and eventually smears onto whatever's underneath, usually in the most conspicuous location. Minimizing the hairs by getting retraction dead-...
