Update Notes on how this is working.
The extended size means the effective work area is almost all “in the green”. Haven’t checked how accurate it is in practice yet.
Some observations on calibration. I didn’t notice Bar had reset the size parameters in config to 400 x 400 with a grid size of 3 and was very excited to get a 2.1 Fitness on V1.09
On redoing the Calibration with a 1500 x 800 and grid size of 7 x 7 the machine went into a seemingly endless run with Fitness values less than 0.02 until I stopped it and reset everything and this time pulled the maslow tight against TR BR belts. Within minutes of restarting it had got a fitness above 0.5. It went on to peak above 2.0 initially and eventually returned a Fitness: 0.7922315046227105.
Can’t stress enough the importance of pulling TR TL belts tight before start of Calibration.
Note The calibration icon is greyed after Apply Tension (still works though).
One problem I have to address, the worktable is on wheels and even though they are locked, I still get some movement (of the table) as maslow changes direction etc. Not insurmountable but something I have to fix.
Release tension then apply tension causes Z height to be unreliable. The first time it registered the height as negative despite being raised 30mm, it then raised the router z access all the way up. The next time I tried it with the maslow set +4mm it reset it to 0 without moving the Z access. I think Bar is already across this and it will be fixed in the next release.
It would be good if I could pause the job and adjust the Z height. At the moment can’t move anything while paused.
