Joe, that's one mighty fine looking CNC machine, I've enjoyed the build so far and now looking forward to seeing the first chips flying in the not too distant future!!

Does anyone have any strong views on grubscrews they would like to share!? I want to get my HTD5M-15 timing pulleys ordered. Do you tend to go for the largest size the pulley can take? For a P14-5M-15F, for example, with an 8mm bore, you can get 1 or 2no. M3 or M4... I'm thinking 2no. M4?? But the P28-5M-15F for my NEMA 34 which will have a 12.67mm bore and a 5mm keyway can go all the way up to 2no. M8 grubscrews which sound huge!? Any thought from those who have gone before? Cheers

2 x M4 on the small ones, flats on the shaft and flattened bits of copper (Clive's tip) under the grubscrew tip and a single 8mm over the keyway...

Nice one -

Got some random bits and pieces ordered - Pulleys, estop buttons, cy cable, copper tape, momentary switches, Ethernet panel connector, heat shrink, insulation tape... I'm going to bite the bullet and get the drives and controller ordered soon...

Joe Have you decided what drives and controller you will be using? Looking forward to the box build

Thanks Clive, me too! The CS labs IP-M for the controller and either EM806 or AM882 for the drives. Probably AM882s as they seem pretty much the same but a lot cheaper?
