QuoteKoenig Quotecman8 Does everybody agree the steppers are a huge upgrade? Better prints? I've upgraded mine twice.... Once to get rid of the heat warping problem, just bought three motors from Folgertech, the same that came with the kit for extruder. Just recently I upgraded the steppers to 0.9 degree steppers to get a bit more resolution/precision The first upgrade I did did nothing for tby wrangellboy - Delta Machines
I have a question about auto leveling. I've mechanically leveled the bed as well as I can. I replaced the z-probe with a FSR setup using a JohnSL controller and I get very consistent results from running g29 and pasting the output into excel. However, it doesn't seem to affect the print whatsoever. I still end up with inconsistency in test patterns and uneven first layers pretty much every prby wrangellboy - Delta Machines
QuoteSeriouspete I melted and warped the original corners on my kit, then replaced those with aluminum, and replaced the steppers with some really nice strong steppers. Now my machine is super quiet and the motors barely get warm over hours of use. If it's a quick print they are cool to the touch, since they are all metal. I can't recommend replacing those steppers enough. I replaced the stepperby wrangellboy - Delta Machines

Quotecislom Ok - a little update on my quest for buttery smoothness on my linear rails. Sit back, grab a beer and listen to the tale of woe, pain and finally triumph. I have tried a few things to get my rails to stop binding up or studdering (took out the wire that holds the ball bearings in place, used super lube, sacrificed a chicken, or two (delicious...)) and I have finally found the correcby wrangellboy - Delta Machines
Quotefattmann Thanks! I was hoping so, as I think one of mine is shot... The voltage will vary WILDLY. Like 1/32nd of a turn to the right will take you from .005v to 1.5, then another turn in the same direction will get you .6v. I assume the potentiometer is just bunk. What is the general consensus on upgraded stepper drivers like the G3D versions? It won't be right away, but saw some positiveby wrangellboy - Delta Machines
Quotefattmann What is the fifth stepper driver specifically for? Got the kit assembled, and was setting the voltages on the stepper drivers to the initial 0.35v (0.55 for the extruder motor) stated in the build manual, and discovered there isn't a recommended voltage setting for the fifth one. It would make sense that you would only have one per motor, but thought it was odd that they specificalby wrangellboy - Delta Machines
What can I expect as far as print speed? I can get decent prints by running at around 20mm/s but that seems very slow. The design goal was "320 mm/s in all directions" but it seems if I get anywhere above about 30 things go south...by wrangellboy - Delta Machines

I had to widen mine significantly, the bolt holes lined up fine afterwards and I haven't seen any strength issues. I also had to file the corner pieces considerably to get the towers into them. All part of the adventure!by wrangellboy - Delta Machines
I've tried various different voltages on the drivers. I'm at .25 right now, which is lower than specified, but any higher and the motors get way too hot. Someone in this thread had reported better luck with the lower voltage, and so far I've actually had more luck at .25 than .35 due to the motor heat. Thanks for the info on testing the blocks, I'll check them out when I get home from work...by wrangellboy - Delta Machines
I think I've narrowed it down to one of my linear rails sucking. One of the three has always been worse and I think that's the root cause. I think it was causing my stepper on that tower to overheat and skip steps. I've finished a couple 1/2 hour or so prints now by turning down the speed and putting a bag of ice on that stepper.

Thanks for the reply. I'll keep trying to figure out what's wrong with that corner. On an unrelated note, I tried to use your updated version of marlin and was unable to get the z axis to zero out. Like another poster the closest I could get it even with negative z values was about 10mm above the bed.

Shifting probably isn't the right term. Basically everything starts printing offset by a couple mm, the offset is always directly away from the rear tower. I can achieve a similar offset by entering matching -x/-y in pronterface (ie g1 x-1 y-1). It seems like it has to be the stepper missing steps, but I don't know what to do about it. I've triple checked the belts, they're good. I switchedby wrangellboy - Delta Machines
I'm having an issue with x/y axis shift. All my prints end up shifting towards the "front" of the print, in pronterface the equivalent of equal amounts of -x & -y. My rails operate smoothly, although the rear rail does take a little extra force. I've tried turning up & down the stepper driver for the rear tower. Slowing the print down drastically seems to help, but even that isn't 100by wrangellboy - Delta Machines
