Hey, I seem to some "ripple" effect on all my axis. It is more visible on the extruder as it is pushing the material very slowly. I am using an azteeg X3 V2 with the DV8825 digipot with 32micro-stepping with marlin. 24V power supply (tried 12V as well). Motors are 1.7A, and I am running the digipots at 1.7A. I the modded the stepper by putting the decay pin to +5V, it seems to work when outside the printer, but when everything is connected it doesn't work. The motors don't turn at all or the micro stepping isn't respected, in one case I actually fried the azteeg... I looked in marlin to control the decay pin, but no pins are declared. I tried to contact pannucatt with no news. I used un-modded A4988, skipping steps as well. Am I really the only one that is skipping steps? or nobody as noticed it yet? (with no mods, outside of the machine, it is skipping steps). Is it software related? Can I change something in marlin? or is it electronic? Links for my research : [hydraraptor.blogspot.fr] [reprap.harleystudio.co.za] The steps are visible on the 3D printed parts because I am using direct drive with no gearbox (I suspect that people with a wade extruder are not seeing this problems as you have a ratio).

When the decay pin is connected to +5V it doesn't move. I still don't understand why it is skipping steps..really annoying.
Micro-stepping in 1/32 with a modded SD8825 works fine. Top speed is very limited.

Azteegs aren't actually fried, it was just the SD8825; still unclear of why they stopped working.]]> tleneel Controllers Mon, 13 Apr 2015 07:52:53 -0400 https://reprap.org/forum/read.php?13,494705,494705#msg-494705 https://reprap.org/forum/read.php?13,494705,494705#msg-494705 I seem to some "ripple" effect on all my axis.
