How I move around my heavy DIY CNC

[Andrewg]

You have got me wondering whether a combination of your linear actuators and a lever system like on that bandsaw stand might be ideal for a mobility solution if one need to build a steel frame anyway. Maybe one for each side, as with the additional leverage two 1500N actuators would be good for weights up to 500kg easily.

Is that a server PSU? I have been told they are a cost effective solution if bought refurbished off eBay.

I had a similar idea as well, using two actuators, but did not do it because I need the space under my CNC for the vac. Also, the one in that link is I think too weak, but I can be wrong about it. It is however definitely good enough for a band saw or similar.

Also, beware, these are cheap actuators, only a motor with gear box, a stainless steel threaded rod, and an aluminium tube driven in and out with a Delrin nut inside the aluminium tube, so I would take that 1500N with a pinch of salt. I did a test lift with an unmodified actuator, and that worked well, it could lift one end of my CNC, so the actuator seems to be good for at least 60kg. Not sure I'd trust it for repeatedly lifting the specified 1500N, which is 152kg, but I definitely trust them for 100kg each, so a 400kg machine should not be a big issue with the proper PSU.

Yes, it is from HP G7 servers. We threw away quite a few last year and I saved a few PSU. They are excellent and easy to use, but beware in case you want to buy a few, the 12V GND is connected to the earth, so connecting these in series is a bit tricky. Of course, the problem is solvable, but you have to be aware of it
