AndyUK's Build - 1.2x1.0m Gantry

[AndyUK]

Back emf: from the coil of the contactor/relay.

But I don’t know the particular UB1 output spec. If a mosfet might find it has a commutatinf diode built in, otherwise place a 1N4001 across the coil, cathode to 24v line, anode to ground

Perfect, Thanks

Does this answer one of your your questions about VFD?

Cheers Nick!

Little more progress on the Z axis - managed to mill the channels required for the Z ballscrew yesterday. Bridgeport wasn't trammed perfectly, so the surface is a little off, (I was under quite strict time constraints and the tramming worm screw is broken - so its as good as I could get without it) but it will certainly do the job I need it to. Assembled the Z axis for a test-fit late last night, but forgot to take pictures, so they'll follow.



My monster of an electrical cabinet has also arrived... 800x600x300 is massive, but should fit everything!! Went for the glazed door option, although unfortunately it has some dings in the door - I'm guessing its just a grey hammerite paint touchup job.



I know I promised frame photos.... but I'm still halfway through painting the bed, and I'm not massively pleased with my 'smooth' hammerite finish. Despite our best efforts, the paint ran all over the place and whilst the surface is smooth, the light clearly reflects the brush strokes. :/ Any advice appreciated!
