Have a look at Open source large format CNC-machine and 3D printer Alex
Not useless - there are several examples on here of large format machines. The Openbuilds designs are for hobby machines and the kits are designed...
Neither the Ox or the Workbee are suitable starting points - the aluminium extrusions used for the framework are just not stiff enough. The...
Bigger target ? (easier to hit). Alex. :rolleyes::rolleyes::rolleyes:
I was worried they might test them on you! Alex.:ROFL::ROFL::ROFL:
If you make it out of wood it's going to be painful for someone. Alex. :eek::eek::eek:
After a few months of doing this the conventional way (with ridges after surfacing) I came to the same conclusion as @Christian James - I had...
The principle is sound, but I don't recommend using masking tape if you have to take it out to measure it - it stretches. Use any rigid scrap you...
With the Duet you could home Z at the end of the job and then homeall. Your G - code for the job should leave your router over the workpiece and...
I suspect the anti-backlash nuts are moulded around a length of leadscrew - hence the tight thread. The ones I got with my machine were very tight...
And a slightly unsteady hand (not enough/too much coffee - or other refreshment :D) can spell disaster! :ROFL::ROFL::ROFL:. Alex.
I'm not sure he has done that @GrayUK - the anti-backlash nut is also the means by which the leadscrew transmits movement. Otherwise I completely...
You might need to fix your workpiece down more securely. Hot melt glue has a lot of "give", as does soft material. That still wouldn't explain why...
You need to use the BLUE masking tape @Colin Mccourt. I haven't used the technique on my router, but I use the blue tape on my 3d printer - it's...
Welcome to the forum. What controller are you using for your workbee? Fusion has cam capabilities built in and there is very likely a post...
Unless you want to import a kit from the US then you are looking at the Workbee in Europe. (The Openbuilds designs are open source so there are...
PS - on the workbee you lose 240mm on the Y axis and 200mm on the X axis from the overall dimensions. If you went with an ☓ axis of 1500 you could...
The maximum using Openbuilds components is 1500mm. You would need to use belt drive at that length, reducing your accuracy to +/- 0.2mm. Also you...
Not the bottom end of the hobby range though - the Dewalt should be up to the job. Not familiar with the Delta, but I see it claims to use iron...
You could always use the router to surface one side at a time if you can hold it down so it doesn't move (would be a lot slower than a...
