Re: My build

Couldn’t quite make out your pictures when I click on em, try rescaling to reduce size before posting as phpBB does weird things in different browsers with large photos. As Y is working and X isn’t, I suspect your nozzle / camera aren’t orthogonal to the table or parallel to each other and it’s wors...

Re: My build

So if you've made the zip tie mods here, with the small zip ties: https://liteplacer.com/phpBB/viewtopic.php?f=4&t=6019&start=40 and it made no difference, then the first thing I'd suggest to remove one attachment, and simulate the new attachment method around something small/flat so you can...

Re: My build

Exactly the same symptoms as the problem I was having. Check out my post about cable ties being used on the belt attachment points, it may look okay visibly, but unless you happened to get lucky, it’s hiding from view underneath where you can’t see it if you followed the standard build instructions....

Re: Integrated stepper motor

What chinese drivers do you have? :roll: Way too many. Left to right, beefier steppers, encoders, servo motors, higher end Chinese drivers, A4988’s (13 of them) and a variety of Geckos. I don’t bother with the DRV’s, because I know from previous experience that they are poorer than the A4988s. The ...

Re: Integrated stepper motor

Why so low jerk by the Y axis? Google Mass, Inertia, Acceleration and Torque. No! I must try it myself. I assumed you meant the higher end Chinese drivers, not the cookie cutter step stick type A4988 / DRVs. The DRV8825's you will find will have poorer micro stepping accuracy than the A4988's, and ...

Re: Integrated stepper motor

So i’ve permantly added Gecko’s to the install for X and Y, an enable/disable switch and done some additional testing after Nulling the drivers with the trim pot. This is all the stock 0.9deg steppers, belts and gears. Max speeds: X: 30000 mm/min and Accel: 18000 Y: 30000 mm/min and Accel: 4000 Note...

Re: Integrated stepper motor

Very cool! I do not think i will spend $140 for drivers, but i will try cheap chinese drivers i bought without any particular purpose. Seriously, don't do that, the cheap chinese external drivers are generally junk, infact if you need those I have bunch you can buy off me real cheap, I stopped usin...

Re: Integrated stepper motor

So I just tried a 1.8 (not a particularly great one) the only one I have that’s this small. Kysan 112040, a bit worse than your 42BYGHW609. Standard spec (stock gear/belt) you were achieving 45000mm/min With the Gecko I’m getting 60000mm/min @ 4000 Acceleration and no whining. I can’t get past that ...
