The less backlash the machine has the better, with anti back lash nut you do sacrifice some speed in the z but it will be faster than you will...
If it occurs again it could well be a pinion slipping, they seem to do it intermittently where they graunch enough metal burrs to hold for a while...

Thanks, your machine looked like an 8x4. Oh okay it looks heavier than 47kg. Should be okay then. Im getting only a very small amount of extra...
Two 20:1 planatary gearboxes with 3nm nema 23,s move it fine. 43nm each with gearing. Cuts upto 6m/min which at the moment is more than the...
No it's looking good, should make for a good machine. It also looks quite versatile where you could easily upgrade to square rail if you wanted to...
Good job, nice that you are giving the old gantry a new lease of life. The only issue I think you may have is in frame regidity, I made one very...
I've now migrated from fusion 360 to inventor which does have automatic dimension and constraints, but i was semi sure fusion 360 did it also, But...
Fusion 360 is free that does tons of stuff You can use any cam to make gcode, they are not machine specific, you just install a post processor...
Cool, glad to be of help. 2nm is okay. I have 3nm moving 125kg each with no problem.
I'm having the same problem with 22mm mdf. And I have 2 on top of each other and an 18mm medite premium on top. I originally used kronospan which...
^ very relative point.
The part about lead screw pitch and motor size on second thought it is definitely a factor for ballscrews, And it Does exist in Leadscrews also...
o fair doos. on the lid?
Probably needs a window tho
if a cnc solution proves to be too expensive. ever heard of a 3d pentogram? this could be used with care to trace tracks from a drawing or wood...
Typically the larger the pitch the larger the holding torque required to achieve the resolution so the bigger the motor, for 10mm pitch and over...
Suppose it's all down to resolution, if they are capable of close then maybe adding gearing of something like 20:1 would be advisable just to...
Very smart.
I am under the impression pcb drilling etc required C3 accuracy screws with fully closed loop servos and at c3 accuracy your then talking high...
