Geeetech

Yes, please post it here.

Also, is this a custom part of the Marlin firmware or something? Why is the problem caused/fixed by Geeetech changes?

Rick,

Yes, but defining 2 extruders does not seem to trigger the problem. It only seems to happen when the 2nd extruder is told to actually extrude something.

I can still print "normally" using just the first extruder, even with 2 defined.

I know this one behavior: print with extruder 1 is OK, and if you manually control extruder 2 then the other axis will move up and extruder 2 have no response.
This is a bug and we'll fix it asap!

I have been printing with one extruder successfully for a few weeks. Tonight I started working on ...

Last night I noticed that the belt gear was very loose on that motor so I re-tightened that. I'll see if it helps.

the stepper driver's current generaly ranges from 0.8-1.5A

Ok, but I can't easily measure the current. Can anyone tell me their voltage which is working well?

When I get my new ...

It doesn't feel that much heavier than 2 extruders. I believe the heat sink is made of aluminum.

I didn't think to weigh it before hooking it up, but I will try and weigh it when I attach it to a more permanent mount. It won't currently make the accuracy of my printer any worse, if you get my drift.

I am working on a modified spider and bracket for a 3rd party dual metal hotend. Please see this post: https://plus.google.com/photos/11826853 ... 9803450657

I will update in this community after I get it printed/working.

Can somebody post good/working slicer settings for the Rostock Mini G2s?

Particularly, what are the maximum feedrate speeds supported by this printer?

Thanks!

I have been working with this printer for a couple weeks, and have it mostly working. One of the biggest problems I am having is that one of my stepper motors (for the X tower) skips steps on occasion. What might cause this to happen?

It is most noticeable when I home the printer and the carriage ...

It's not a cheap solution, but I ordered 6 packs of these: 6 x 8 x 0.2mm shims.

I put 5 of them (for 1mm) on each rod-end bearing holder before putting on the rod-end. When the screw is tightened there is no more ...
