very true about the creep up vs down especially with the gravity of his spindle! Could the timing thing be helped if they went from 1/16th to 1/8...
If the Z is getting that hot, set the current one step lower on the drive switches, maybe your acceleration is too aggressive on the Z causing the...
I'm using the dq542ma drives, with an Arduino Uno and GRBL.. just make sure to get a real Arduino they are like $16
I guess it all depends on the vendor, that's a great price that you found, i found those 8020 slides for $60-80 per block online.. yes the real...
Jason, What made you go with the 8020 linear slides? How did they work out as far as friction?
Did you install the drivers for the adapter? does the adapter show up when you plug in the usb under device manager? parallel-usb adapters can be...
Finished my new mount today, mostly happy with the outcome. I cut the mount hoops before i tried Climb cutting ( :banghead: ). I did the mount...
great idea! never thought of just adding square stock to the v-rail. One thing i would suggest is that you probably don't need to double up the...
I read through your discussion a little and i see this? - (5) NEMA 34 640 oz-in Stepper motors (KL34H280-45-8A) - (5) KL-5056D Digital Bipolar...
Nice build don't know how i missed this one! I scanned through the build but didn't see what voltage you are running? Voltage is speed,, so if...
Not worried about breaking the screws, but you are probably right, just have strong end stops! 397oz-in steppers at 48v (high speed) I worry with...
Honestly ball screws are overkill with V-wheels and V-rail. I would use linear bearings like MGN9 or 12 size. Can be found for not much more...
Probably wheels are too tight, causing backlash or missed steps.. also on a 1500x1500 you are crazy not using dual-belt IMO
Did some Trochoidal milling today, just doesn't seem possible when it starts cutting that DOC, amazing.. Using Estlcam to make the g-code, makes...
did you try less microsteps? do you have the 16 tooth or 20 tooth pulley on the stepper? 16 tooth will get you some more force.. Powge on Ebay a...
could always do a counter weight with a pulley or a linear spring
I would start by turning your max speed (110-112) up to 1000 and the acceleration up to 500 (120-122) also at 1/16 you should be at 200*16 =...
Weight isn't the issue, the nema34 size is much bigger and will not fit on the standard ox plates which are all made for nema23. nema23 makes...
why nema34? it's overkill for this size cnc
I think 1mm is too thick, more like 0.5mm is what you want. I used glue for mine with carbon fiber strips as 0.5mm spacers. Been running great...
