Topic: Updated firmware. Now I have Z wobble. Update! 9-20-13

I installed my e3d and had to update the firmware for the E3D temps. Now i have developed some Z- wobble.
How do I get rid of this using the firmware. My prints were fine before.

Re: Updated firmware. Now I have Z wobble. Update! 9-20-13

that doesn't look like z-wobble. That looks like moire from the extruder. Try backing the trimpot on your extruder stepper driver counter clockwise a 1/16-1/32 of a turn.

Other methods for setting extruder trim pot -

[*]set to 0 - full counter clockwise (careful not to go past stop)[/*]
[*]in RH set manual extrude speed to 5mm/s[/*]
[*]extrude 100mm [/*]
[*]slowly adjust the trimpot clockwise (1/16 of a turn at a time) until you hear the extruder start extruding smoothly[/*]

I will give it a try. Any Idea of what would have caused this? It was working perfect before I put the E3D on?

the filament might be a have a little more resistance with the E3D since it is stainless and not PEEK lined with teflon. that is my guess. I had the same thing with my E3D.

Re: Updated firmware. Now I have Z wobble. Update! 9-20-13

I haven't got around to this yet. What exactly does this trim pot do? Does it adjust speed or power? Is this on the motor itself or on the board?

Re: Updated firmware. Now I have Z wobble. Update! 9-20-13

you should look at this thread I made about a week ago on uneven microstepping

http://www.soliforum.com/topic/3491/ext … g-to-fail/

I did only start to notice it when I went to the E3D

Re: Updated firmware. Now I have Z wobble. Update! 9-20-13

I will have to try this still. Haven't had time.

What about the slight banding. I am going to pick up an M5 rod which hopefully will help.

Try printing some calibration pieces that are vertical and see that you get.

Re: Updated firmware. Now I have Z wobble. Update! 9-20-13

I have some parts I will get pics of. I messed with the stepper Pot. I need to upgrade. I couldn't get it to go away. I'll get some pics up.

I ran a print and tried to adjust on the fly. I turned it down untill it started skipping and went up ever so slightly. It looks a little better but not gone. I am almost back to where I started.

Are the stepper drivers drop in besides changing the firmware? What do you recommend?

Ordered the Pololu 1/32 driver. I'll report back when I have it installed.

Stepper installed. Looks much better. Something is still going on. I'll get a pic up when my print is done.

Did you tune your VREF?

I had to turn mine way down; to just above where extrusion stopped.

looks okay to me. Time to replace the 5/16" threaded rod though.

Re: Updated firmware. Now I have Z wobble. Update! 9-20-13

Yes mine is just above not extruding. I have a m5 rod and m8 for replacement caridge. Should be here early next week. The new stepper is awesome. I hope the m5 cleans up the rest.
