Gerald has been collecting enough fixes, and has enough worn parts that it's worth taking it out of service for a week or more to perform a major service and get our large cutter running more reliably again.

We'll need to collate a list so there's a clear idea of all the things than need doing as part of a service, where appropriate, these should link back to an issue (open or closed):

  • replace the lower bed toothed belt(s) #288
  • replace the screw, refit and loctite the bearing cover on the y-axis slides #287 #429 (requires disassembly of the y-axis linear bearing assembly)
  • loctite the bearing plate mounting screws on reassembly #517
  • fit the safety cut-out switch more securely #516
  • new mirrors and lens for gerald?
  • clean down the whole inside of cutting residue,
  • fit a 15mm drive belt to the x-axis #501
  • build a permanently vented exhaust setup #474
  • replace the short motor initial drive belts
  • refit the front panel lock
  • replace the control panel for one that's not peeling off
  • fit new o-rings behind the intermediate mirrors #387
  • Any more?

It's already looks like a big job, and some of these require more than one person. It would be great to get a working group together from the wider community. Can you help with this service?

Organisers' meeting notes: @jackie1050 and @huffeec have offered to help. John Cain possibly too.

All to suggest any further things that need doing.

I'm conscious that Patrick, you're off for most of August, and we want to give people plenty of notice for a refurb is the laser is going to be down.

Should we try and set a date for this even if it's in September, so when people are frustrated they know there is a service coming?

Thanks, Steve

Happy to take a week from September, how about the 25th?

Need to order a lower toothed belt from China #288 (which hasn't happened yet) as HPC was unable to supply the belt. I think all the other parts can come from the UK (eg ducting, mirrors, lenses and o-rings) or we already have in the laser cutter cupboard (the screw that came out, upper belts)

No-one has said anything about the belt. As I understand, this is still an issue.

According to Karl D. the right hand side of the bed is visibly lower and needs 2cm of packing under the stock to level it.

Not sure which issue to add this to ...
@zarino and I were trying to cut some ply yesterday (parts of the crate Martin's CNC came in ).
This was approx. 5mm thickness. Settings : speed 5 power 70 corner power 65. It cut ok in top left corner but even after 4 cuts it didn't cut through in other places (more than 300mm from top left).
