I've used their 2040 with no issues. The complaints that you have are vague . Top and bottom surfaces aren't even remotely parallel. You only need one side to be parallel Angles are not 120° If they are not what are they ? 119.5? Mind you that the corner angles are pretty standard. If you truly want something "precision", go to some expensive CNC shop, give them a tolerance spec, ask themby Vigilant - Delta Machines
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 Vigilant - Delta Machines
Quotedc42 Quoteo_lampe QuoteI think I'll use Bondtech extruders because I like that they push from both sides. I don't have experience with these, but IMHO the second drive gear is pure marketing bull$hit. It would be much better, if it had it's own motor. But now it's just a "follower" which adds friction losses and the motor invests more torque to bite into the filament instead of pushing it.by Vigilant - Delta Machines
QuoteHaydn Hi MKSA, I contracted with a machine shop in China to have these ball studs custom made. They work great in delta printers, because they're inherently zero-backlash. I sell them for $1.50 each. You can order them directly from me. Postage to Europe is around $14 for a few sets. In Europe, you might be able to order them from: They've got a shipment coming in.

You should worry more on frame rigidity , repeatabilty, reliability and accuracy of your config values . Delta maths are handled by firmware not you, so you shouldn't worry about it.by Vigilant - Delta Machines
Do not use MGN9 not because they can't be used but their dimensions does not suit the 6mm gap on the extrusion. Use MGN12. I made the same mistake. I use robotdigg Stainless steel linear rails for my delta and it's ok. It's cheaper than hiwin equivalents but more expensive than the typical chinese rails.

Quotekapperi Quotethe_digital_dentist I wouldn't let my dog (if I had one) use 2020 to build a 3D printer. Go with the larger stuff. Ball screws will probably allow the bed to drop when power to the Z motor is cut, if everything is aligned well. I definitely would not mix bearing blocks and rails from different manufacturers. Linear guides are systems, not parts. So do you think I go with tby Vigilant - CoreXY Machines

QuoteOrigamib The biggest challenge with an XYZ moving gantry is keeping it rigid. A flat bed on Z is easy to keep rigid and can be kept relatively light as a result. With an XYZ frame you have a square that will act a bit like a picture frame when you take the glass out. You can reinforce it, but in practice its a lot easier to have a bed that moves in Z. Yup your right, I'm guessing that is thby Vigilant - CoreXY Machines
Quotethe_digital_dentist I made a printer with 300 mm square bed using belts to lift it in the Z axis (700 mm) and it's working well (click the Ultra MegaMax Dominator link in my sig, below). I would not lift the XY stage unless the printer is really big making it impractical to lift a much more massive bed. I have tested the Z axis in my printer to lift a 4 kg print mass (and the bed assemblyby Vigilant - CoreXY Machines
I'm curious on this design concept where the z- axis carries the gantry instead of the pritnbed Gantry is lighter but houses moving items, print bed is heavier and require gearing and a method to hold the bed during power off. has anyone tried both and can comment on it?by Vigilant - CoreXY Machines
Quoteklcjr89 QuoteVigilant I do think the idea is good, but it doesn't address abnd resolve the number 1 problem with Z axis which is z banding. It should if the bushings the ballnuts rotate within have a clearance inner diameter. Example: if the OD of the ballnut was 40mm, choose a 41mm ID or comparable bushing.

You’ve changed the kinematics, technically that’s no longer a hypercube. Where did you get the carbon fibre rods? Did you cut them yourself ? Is there a reason why you’re not using 1 huge diameter carbon rod instead of 2 small ones. I do think 2 14mm diameter looks neater than 4 10mm just like ultimaker. Project looks good .

Even if you increase the stiffness of the belt , what happens is that the ringing frequency increases and the amplitude decreases, but the duration of the "ringing" might be longer so it might be a zero sum game. And if you think about it even if you have infinite belt stiffness, what is stopping the stepper motor from ringing? the only thing preventing the stepper motor from turning is the elecby Vigilant - Delta Machines

Duet also prints from sdcard, the gcodes are not streamed from the PC. You need the fast networking speed to transfer the gcode from your pc to the local sdcard on the duet . Having used smoothie and duet , I must say that duet is now further ahead in features than smoothieboard. And printing is so convenient now, no need to insert and remove the sdcard, just upload and print.by Vigilant - CoreXY Machines
