If you’re talking 5mm holes it’s fairly easy to knock out a jig from a 1” scrap of 20x60 and a small block of wood. At work right now but when I...
They’re really not that hard to make yourself. What are you wanting to do with it, end drilling?
Over-tensioning the lead screw will also do it. Really should be using thrust bearings in these systems.
There should be four. One for each motor. At what output voltage? Overall, this is a question beyond my skill set. But it sounds like all you...
Two questions, does your system not already have individual drivers and what voltage are the steppers being driven off of?
At a minimum you will need an Arduino Uno and 4 proper stepper drivers as well as a 24 or 36V 350W power supply.
If you're using the standard OpenBuilds mount it would be fairly simple to cut a 71mm diameter drop-in block with a center hole to accept the...
You might look into marine grade aluminum epoxies. You'll want to scuff the anodizing to get a better grip and use temporary backer plates to hold...
Just to restate the obvious you will need longer bed rails too. And depending on how your wiring is set up you may also need a longer drag chain...
If you’re using stock OpenBuilds parts the dimension would be 40 (for the extrusion) + 12 (for the wheels) = 52mm. It’s always a good idea...
^^^add 12mm to the extrusion width for mini wheels. 20mm for full size wheels. And as Peter notes you’ll need eccentric spacers along 1 side of...
Dragging by hand is never a good idea. The power generated by the spinning motors will smoke your drivers. Always use the jog function to reposition.
Yes go with the Mini Mill just you’ll want to add the two extra pieces as noted above if you need a full 6”. As for general support that happens...
No. The C-Beam while a great machine for the time it was originally created is not all it could be now. It truly needs an update with more current...
More workable area (8.5" sq. vs. 5" sq.) and more rigidity due to the two columns and the way it's framed. That being said, the Mini Mill can...
Okay, that tool is way more manageable. The Mini Mill should be fine. If you'd like something a bit larger and a bit stouter for just a slight bit...
While I can generally handle physical build questions I'm not fully versed in what you're trying to accomplish. Are there any good references I...
57 pounds is way too heavy for anything OpenBuilds. Can you give us a better idea of what you're grinding and how much material you expect to remove?
Not an OpenBuilds system just OpenBuilds parts. Home build design. Z-axis is way too tall, processor/driver board is under powered. Would suggest...
Very nice work.
