Not to dredge up a dead topic, but I received my 17HM19-1684S steppers and hooked them up. That didn't solve the problem. At this point I have parts on order to switch to 24v & a duet wifi so I figured I might as well have some fun. It looks like the culprit was M203 E3600. I switched it to E15000 and things are humming along nicely now. For posterity, my config now looks like this: M9by wrangellboy - Duet

The printer is a folgertech kossel. Or was, really only the frame & linear rails remain stock. I was a bit surprised by how hard I had to drive the steppers as well. I've tried backing the xyz steppers down to 1500mA, and it doesn't solve the problem. The strangest part to me is that sending just E steps works (G1 E0.05192), but sending xy moves along with E steps fails (G1 X-26.214 Y3.542by wrangellboy - Duet
I knew 1.8A was pretty high. I do have a cooling fan across the top of the board, not the bottom. I'll try to get some better cooling and drop the mA back down to 1500 and see if that resolves things for now. I believe the drivers on the Duet Wifi can accomodate more amps, is that correct? In either case it seems the 17HM19-2004S steppers I have are not really suitable for current Duet boardsby wrangellboy - Duet
Hey all, I'm having issues I suspect with the extruder driver on my duet 0.6 (from replikeo). Everything has been working perfectly, then a couple days ago it stopped extruding while printing. But only while printing. When I pause the print, or just using the web ui I can extrude just fine, but when printing the extruder motor just vibrates and doesn't move. It does move when it hits a retraby wrangellboy - Duet
For me slower is better for bridging. I have mine set to 20mm/s. Quotespiffcow So last night I finally got a perfect delta calibration print (this one ). I'm pretty psyched, but I notice my prints are still not as smooth as I would like. And by that I mean that they have a physically rough texture. I'm wondering if this is due to the jiggle of the traxxas connectors and the error in length betby wrangellboy - Delta Machines
I'm using this, and I've had good luck. I have one of these sitting on my desk waiting for installation. The FSR's work well and I get excellent performance out of them, but they have a couple drawbacks: 1.

I have a mini kossel running duet electronics (0.6.x) with reprap firmware. Everything was working great for the last couple months when all of a sudden a couple days ago my steppers started missing steps. I've corrected the problem for now by increasing the current to the steppers with M906 from 400 to 1000. My 12v power comes from a 600w atx power supply.

QuoteDelta_Stu New owner of a FT Kossel here. Read through the entire 81 pages. Was there a concensus on the length of the diagonal rods that allows a good compromise between width and height?

QuoteRattfink Quotewrangellboy Do your carriages run smooth if you disconnect them from the rods? Do all 3 motors jerk at the same time? If it's all 3 it seems most likely to be a software issue.

On the topic of extruders. Does anyone know the practical upper limit of the stock folger unit? I've got a roll of PETG I've been experimenting with and it likes to print really hot.
