Ooh I didn't know about that problem, I will have to check my stepper currents again. The strange thing is that this doesn't seem to matter what speed I print at. I could also take it back to 16 Microsteps and increase the acceleration and jerk to ensure it it doesn't print in the slow danger zoneby edak - Delta Machines
It does use the DRV drivers just like the micromake, but the original printer never had the problem and I have no record of what changed. I have no idea how the driver could cause this problem and yet be only at such regular intervals.by edak - Delta Machines
If I change the steps per mm then I will introduce over /under extrusion. Effervescent I did test this by trying out 32microsteps instead (smoothie handles this no problem) but no change at all. Could it be more along the lines of a bent extruder motor shaft or a buggered extruder gear? On the other hand it does only appear on one side of the print so now I doubt that. If I print the same modelby edak - Delta Machines
From page 4 post 1. I look more into it now and I think it could be something as bizarre as extruder gear or something that happens repetitively so is more visible on layers that are somewhat repetitive like cylinders. Quoteedak I am having some issues with my printer and I thought I would put it to the brais trust. I have a problem where the layers are shifting very slightly and this is creaby edak - Delta Machines
Here you go. I notice that the pattern is not a layer shift (more evident on yellow print) and looks to repeat more regularly in areas of a print which use more filament (on purple print the lines are closer together on the wider layers)by edak - Delta Machines
I just wanted to give everyone else an update on my printer with the strange pattern surrounding the prints. I I was unable to get rid of it and now have pulled out all hair. I ended up switching to smoothieboard (usb died on my original board), changed rods, tightened everything and nothing I have done has improved the issue. Small parts work out very well but I will always have this spiral arouby edak - Delta Machines
If you go to thingiverse and print out the link below then you can use the 40mm included fan to a e3d E3D Clone 40mm Clip-On Fan Mount found on #Thingiverse I designed that and it clips on nicely for me.by edak - Delta Machines
So I have replaced the stepper driver chips on the PCB, replaced the arms with traxxas, taken away the heated bed and running at slow motion 30mm/s and still I am getting that funny horizontal pattern in the layers! It's the pattern that it makes that is really annoying me because on some of my prints it stands out quite prominently. See attached photos, note that they are further apart in thesby edak - Delta Machines
I have ordered some new traxxis ball ends and push rods for them so will get rid of the slop that Treloid has identified (I noticed this too). I seem to have blown one of the stepper drivers in my search to adjust them correctly (I think I removed the motor when it was still powered so blew the DRV8825 chip). This is not such an issue as I will just replace the chip (ordered a new one of thosby edak - Delta Machines
Can anyone identify how a motor could skip in the same direction then back again so regularly? I would think that motor skips would look more random than this. Still puzzled...by edak - Delta Machines
xile6, I am talking about all the horizontal lines which are visible on one side of the print as identified by attached image. They are not part of the design and are a small 'shift' in those layers (on the other side there are small dents but those are much harder to see because they don't catch the light. This isn't the stitch point from cura though I haven't yet ruled out the slicer yet.by edak - Delta Machines
I am having some issues with my printer and I thought I would put it to the brais trust. I have a problem where the layers are shifting very slightly and this is creating a pattern on my prints. The strange thing is that it seems to be related to how much filament has passed through the extruder (wider layers that use more filament show it more regularly and pronounced) because it's periodic baby edak - Delta Machines
When I write 0.3mm it is between x and y axes. If you have a heated bed installed then the default firmware becomes repetier, not marlin. That is what I am working with.by edak - Delta Machines
I am still working on the stock firmware but adjusted the rod length to get my prints to the right size then adjusted the next setting to get it flat. It was a procedure that only took a short while so should be easy. My x and y aren't perfectly equal as there's no way to adjust individually with stock firmware, however they are within 0.3mm of target.. I also would like to know if others are usby edak - Delta Machines
Problem solved, the seller got back to me about my question, was an easy solution too! The software I had originally downloaded had two firmwares included (hex) in the resources folder for cura. one was for a heated bed version of my printer. In Cura I just go into printer settings, enable the heat bed and upload default firmware (firmware was in the right folder for this to work. My board looby edak - Delta Machines
Hi all, I just joined and only recently got myself one of the micromake kossel deltas. I want to connect a hot bed to it and I an not sure how exactly this is done. My PCB is a micromake v1.2 and it has two terminals for hear bed but also has a separate power supply for the bed. I can't see anywhere in the default firmware to put the HB temp either. Any suggestions?by edak - Delta Machines
