I have not got power to the cabin yet other than running an extension lead. I am waiting on the boatyard crane to move the cabin round a bit so access will be easier for material, once they do that then I will run in some 3 phase.
Today however I decided to power up a drive at a time from single phase supply.
The racks and pinions on both axes still need adjusted properly but it was fine for this test.
Got the Y set up first, did a rough tune and set up the Index homing. It went reasonably well but I am probably going to have to drive both sides as at 20m/min rapids and jogging back and forth in very short bursts I could see the far side getting out of shape. I will see how it performs at the fastest I will ever cut, probably 6-7m/min, and if it looks reasonable I will delay driving the second side until later.
I can then decide whether a rod/tube through the gantry or a motor on the other side will be the best way to proceed.
Anyway here are a few vids,
First is the X axis going at roughly 20m/min.

https://www.youtube.com/watch?v=bof2LoSPxoEAs can be seen in the vid I am monitoring the encoder via a netbook connected to the drive, the encoder count is spot on each time, jitters between -1996 and -1997 encoder counts. The tuning is not perfect yet but it was good enough for today's tests.
The prox I am using to trigger the Index homing is on the non-driven side so it shows that there is not any flex at the lower speeds of the homing (5m/min)
Hope to get the Z Axis tried out tomorrow, hopefully the tiny motor will be up to the job.
