@Roberts_Clif I was referring to the OP machine ! The starting point is a sound design that has to be properly built, rigid and square. The slicer config comes LAST ! It will not compensate for a flaky unreliable build.by MKSA - General

Quotehenkyprayoga Yeah, I saw that people try to make linear bearing using common PTFE tube used for bowden tubing. But I think that using PTFE tube which has the same ID as the shaft should be simpler. It's easy to get as well. I read that people using IGUS bearing also require properly aligned shaft. So it share the common problem? Is it better to use Igus polymer bushing or print using theirby MKSA - General
Quotehenkyprayoga I'm pretty much like the idea. How is it going after 2 years? My bearings made with IGUS filament work fine, linear, even idlers bearings and TR8 nuts. Use it for other machine too. Note I use 4mm PTFE tube portion for small bearings, 2mm shaft (for a filament detection device) and PTFE sheets. IGUS is less prone to creeping than pure PTFE. As for the PTFE bearings described aby MKSA - General
The Chicom 3D printers have a flexible frame that prevents to some degree, the bearings from binding too much. They are just noisy, the time it takes to grind the guides enough. Here, the frame seems sturdier, therefore binding is as normal as the poor alignment. It is cheap, isn't ? 0.5" diam is quite strange, not standard, is it US made ? Check if the rods are hardened steel, not soft stainlesby MKSA - General
The point here is to use an extrusion (thread forming) tap instead of a cutting tap ! They are of course not just to tap Al extruded profiles. This method gives a stronger thread besides Al is a bitch to machine ! You are more likely to break a cutting tap in Al than in regular steel. These taps are more expensive, the hole must be the correct size and of course it needs good lubrication.by MKSA - Mechanics
They had just to improve the performance, not change everything to make it more "pleasant" ???? They failed ! Typical when look is more important than functionality.

QuoteNEONBLACK Speaking of endstops... Why is it that the manufacturers tend to start using only one per axis? Sure you can set you max. position, but wouldn't it be the right thing to do and use max/min endstops? Or you could do it sensorless, which seems to be a pain on CoreXY's. Not sure i can find a board supporting my idea. I never understood why there was a Max and Min input on the controlby MKSA - CoreXY Machines

Quotethe_digital_dentist .... Other than sitting on magnets in oversized holes, I'm not sure how the design in the video works- it looks like the bed just sits on magnets and is free to expand, but without any guidance, so for example, if power is lost mid print, you won't necessarily be able to resume printing because the bed may not expand to the same position is was in before power was lost...by MKSA - CoreXY Machines

So ? Already done. Igus and others market them with proper guides and bearings. In fact better use the 8mm rods nested in the Al profile as tracks. The type of anodization of these Al profiles is usually not suitable for a track. Of course Igus filament ot make proper sliders too.
