Attendees:
- Blake, Glenn, Kamil, Jason
Notes:
- Little red
- Was cutting a bit slower ~8mm/s for 3mm MDF at top right and bottom left
- Checked heights and adjusted offset from 10mm to 9mm and seemed to improve
- Cutting at around 13mm/s for 3mm MDF
- Still overcurrent at 24mA
- Still tube change being pursued
- Require end extension
- Require tube mounts
- Big red
- No maintenance actions. Seemed to be cutting fine.
- Kellogg the KH7050B
- Kamil has installed door sensors. Wired up one to Steve's interlock board.
- When door closed, fancy interlock sensor flash red-green. When open interlock shows green.
- Interlock board shows 24V and 5V power lights. When interlock sensor closed, no input detected (and no output)
- Tried scope on interlock line (had been told to expect square wave when closed) but saw nothing but noise
- Tried unscrewing the mating piece from interlock and waving close to sensor to see if sensitive about distance - no effect
- Tried the mating piece from other interlock and performs the same (flashing red-green)
- Need to try removing the active piece of interlock to see if its interference from Kellogg chassis causing problem.
- Or is it interlock board?
- Need to pull out an interlock and take a look on work bench again.
- Discussion on z-axis drive
- Kamil has a larger stepper and driver on order
- Concern that it will be large enough to strip belt
- Considering getting larger diameter pulleys for each pole to increase torque on rods
- Also considering replacing the ball bearing rollers at each end of pole since inspection shows they are rough (not rolling well)
- Need to get a spare set of belts for Kellogg too - especially if we might strip z-axis belt.
