Do you want it welding Robin ? or are you going to make a new one.

I can stitch you that back for the price of the postage.

I weakened it by putting in steel insert nuts then went a bit wild tightening the bolts :naughty:

All part of life's rich tapestry but still a silly mistake, looks like I'm further down the learning curve than I thought

I was going to run a bolt down through, maybe fillet the cracks with Al solder but this here welding sounds interesting, I could use a smaller bolt. See what you are up against before volunteering though

No problem with that, wouldn't put the broken bit back anyway, just build the whole end up with filler weld, 15 minute job.

A generous offer, OTOH I am more than a bit impetuous and an M8x40 looks rather inviting. If I can close the gap I could be up and running today :naughty:

I have a spell in the dentist's chair at half past ten, a good opportunity to cogitate

[Robin Hewitt]

M8x40 did the trick, gap closed, put an arrow on the pic in case you couldn't see where it was

Did you drop some loctite in the gap before closing?

Did you drop some loctite in the gap before closing?

Because if it gets the faintest jiggle it will never close that sweetly again :nope:

Good idea, but then I'd have had to clean off the RTD and I was rather enjoying putting it together :naughty:

If I take it off I promise to Loctite it
Kip, I don't know how it compares to driving the handwheel because I've never tried that. If I had to guess I'd probably plump somewhere between amazing and freakin' miraculous

[Robin Hewitt]

Curious.

I wound up the feed rate on that hybrid stepper and it would do 18mm/s but clacked out at 20 mm/s

I disconnected the Y axis to get some spare Amps then switched the hybrid peak current from 1.9A to 4.2A peak.

Wouldn't do 18 mm/s anymore :nope:

Possibilities...

The cable on the Z is altogether too long and it's having problems controlling the current.

The stepper driver can't actually cope when you increase the current.

I imagined it :heehee:

So, any ideas what driver/PSU combination I need to shop for?

However, 18mm/s is a lot better than I had before so I made new plates to fit them on the X and Y. Stuck a fanciful strain relief bracket on the X so I can bolt the flexy trunking to it.
