Sorry but the longer, the worse, certainly for a direct drive, less for a Bowden. On a Delta, any angular error will lead to errors in the XY plane.by MKSA - General
QuoteMoriquendi It's the wiring at the other end that people occasionally get wrong, I don't think that's the case here but it's an easy thing to check and one thing to cross of the list of possible causes. I suspect that either your ramps has a particularly low threshold or the board I sent you has a particularly high logic low output. I'm happy to send you a replacement but there are a coupleby MKSA - General
What you have to look in these cheap copies is how and if they can be made to perform. Forget about the false claims, the blatant lies expressed in awful (any language), they have to be considered as unfinished products, almost raw material. For ex: the grub screws are cheap and a bad idea, they will seize, crush and provide poor contact. If there is enough material, a hacksaw, a drill, a tap "etby MKSA - General

Quotehercek Oh, I'm a fan of auto-probing. I guess I was the first one who introduced it properly for delta machines. What I'm surprised about is an opinion of auto-probing need before every print. Either it is overrated or the average printers suck. I heard a lot of complains about mechanical endstops too. I had become worried about it and modified my firmware to touch them 5 times when homingby MKSA - Delta Machines

All the printed plastic parts will provide the required flexibility to compensate for all the misalignment as this set up is over over constrained. Luckily linear rails can exert enough force to straighten things without binding. Polymer bearings on the other hand would require at least NEMA23.by MKSA - CoreXY Machines

QuoteCyber Akuma QuoteMechaBits Since when does the USA do stuff in Millimeters? Dude, really? Just because it's not the standard unit of measurement in the US does not mean the country and all manufacturers and stores are ignorant of it. I went and picked up Metric screws for my printer from Home Depot a few days ago.by MKSA - General
Of course smooth rods can be used for a frame, they are just like profiles except the hole is filled and they are round Quality smooth rod is hardened steel and you can't thread . Anyway, better secure it in a hole, a slit and a bolt to squeeze it, rather standard method.by MKSA - Delta Machines
As they are still a few people using "inch", although a fast dying bunch, chinese mfg have decided simplify and produce metrinch rods, bearings, profile ... intended to fit both system, eg. 8mm and 5/16. Therefore sometimes you get excessive play, others you need excessive force. Excessive play is OK as most 3D printer frames are overconstrained, poorly assembled, aligned, flexible thus oftenby MKSA - General

Quotethe_digital_dentist I think they cobbled together a couple existing motors to make this. 200 step/rev isn't particularly useful for a clock. It would make much more sense for a clock motor to have some multiple of 60 as the steps per rev. Would be non standard regarding the stamped metal sheets used in the construction. Here rotor and stator are standard. Bean counter senseby MKSA - General

I also intend to use it for some small aluminium pieces. I know those two are at odds with each other but if I go with a steel tube construction like I'm currently planning it won't be hard to switch between the two if I neeby MKSA - General
Published on April the first ? BTW, the description states: for analog clock. This set up makes sense as there is no need for gears and it can be used for a 24h dial clock.by MKSA - General

Wobble is due to a wrong design: incorrect use of coupler, improper leadscrew mount and aggravated by the poor parts quality, e.g. use of standard M screws unsuitable for the task, often bent. So, instead of trying to reduce the effect, it is better to do it the correct way. On a 3D Z axis, the bearing opposite to the one motor side, is not required due to the low speed and it simplifies theby MKSA - Mechanics

QuoteAlmostNeverAgain ... 1) Chinese are writing from right to left, as Leornardo did, to hide written words, but not for the same reasons ! .... 2) Just one question: If a frame-based (bracket, hinge,...) solution would allow to trigger the endstop when PCB/Piezos compression is released, .. 1) wrong, Leornado wrote that way because he was left handed and it is "cleaner" when writing with inkby MKSA - General
QuoteTrakyan So you're prefer a lathe over a mill?... Never said that. Just that this is the right way to build a decent CNC able to machine more than cardboard, plastic sheet, wood. Here, as I said earlier, concrete, granite slab could be used as a base for the linear rails. Even then, you will have to spend. Now, a CNC router as cheap as a cheap 3D printer, will be worse than the said printby MKSA - General
QuoteMelty .... Instead of being fixed in place, could the anti-rotation cables be auto-tensioned with suitably strong springs to eliminate some of that risk? No ! If you do that the system is not isostatic anymore. It would be like putting cloth pin springs on the belt of a COREXY (suggest that to DD and RUN ! )by MKSA - General
