Just an FYI in case anyone is looking for the 3mm bore 16T pulleys (they're a pain to find), I found a UK eBay seller who stocks them, and I've...
That's pretty awesome for those speeds! With a volcano block brings even more speed (I regularly print at 120mm/s with 1200mm/s2 acceleration and...
So what I've found to reduce these artifacts the most has been to increase my jerk settings. I had a unique scenario where I was printing at...
From those (nice) results, seems like we need to tune TMC stepper chop registers for the Hemera extruder motor. Should be able to help solve this...
Hmm interesting. I had tried that before on a Duet2 (TMC5160) and the problem persisted. Maybe I'll try again with quarter settings and see if...
Yup that's what I was talking about. If you look at pictures of 3D prints online made with precise motion systems (like a TC, a Railcore, or a...
Unfortunately those links aren't loading.
Try slower retraction speeds. I found better results with 25mm/s instead of 40+ with the same filament. It can print from as low as 190 to 230. I...
Loctite will loosen up under heat. If you can, use either a heat gun or (even better) a soldering iron to heat up the screw. Should pop right out...
On a possibly related note, are you guys noticing "ripples" on the top surface of extruded material? I see it quite a lot with black PLA or any...
That's an interesting issue. Please do keep the thread updated when you get to the bottom of this! :)
Try reducing idler tension. I found that helped quite a bit. And I have a feeling this is the cost of the higher precision in the machining of the...
Just for sanity's sake: try checking the current being supplied (about 1000A is a starting point for the Hemera stepper, 1100mA would be nicer,...
Alright seems like this entire issue was based on frame mechanical problems. Please ignore this thead.
Hey everyone, hope you're all staying safe and sound these days. I've got a first-batch set of Hemeras that have been acting a little odd lately....
