OK, episode 11 is now ready.

We say a fond farewell to the trusty Mk3 and start building the bed frame for Mk4.

Actually neal it's not that simple and I pretty much guarantee you that if your using timing belts then the steps per won't work out per the calcs.
This is one reason why mach's calibration is best...

I'm using something like Mach3 version .028 and that works fine with the CSLabs macro for touch-off and M6start/end. When I tested the touch-off mechanism, I was getting +-1 microstep repeatability,...

Yes if using Cslabs macros. The problem is with Mach rather than Cslabs but the workaround is to use Modbus and talk directly to the controller rather than going thru Mach.
Bit fiddly for most but...

if your on facebook- these are the probes i use and sell in the uk

It’s a Glowforge Pro... finally arrived after buying one during the Kickstarter over 2 years ago. Thankfully that was at 50% the price that they are currently asking!

I have to say I thought that...

Sorry, qmarjov - I don't yet have numbers to share for cost. I will do a rough estimate nearer the end though.

As you guys may have noticed, not much has happened last month or two. What with...

Here comes episode 10 - machining parts for the bed:

I have the Oukitel K6000 plus 4Gb ram 64 Gb ROM, I bought it from tinydeal European wearhouse, for 154 euros with gorila glass and case ,the phone is a killer !

The elephone is lovely but I would also consider this one instead and it's cheaper!

Dave - take a look at this for starters. It has a couple of pointers to some general info on Mach3 internal architecture and at the bottom of the post a pointer to a pdf with a bit more specific info...

4nm motors can be bought from cnc4you.co.uk or zapp automation :) those motors have good specs compared to ebay versions.. the ebay motors usually have high inductance.

Spindle + vfd seems more...

Yet another bloody post i spend reading for it to hang dead lol, How did it go for you in the end?

Chaz is right there Fusion 360 models I then "coloured" using different woods in physical material.

I was playing with different ways of making cad models from bitmaps

The South Park figures...

Renders from within Fusion 360. Shows how good they are, the need to check / question :-)

Cheers Dave!
Yes would love to do the ATC spindle but need to finish this thing first! I added footage of me changing tools and tightening the collet because 'Jogara' had a post on tools slipping...

oh wow...





Just removed the sides.. the suggestion i read on this forum (Joe H[emoji106]) using a simple packing tape on the sides worked out great. Easy removal of siding and great...

Well, what can one say, definitely a work of art, when are you starting on the glass case:thumsup:

I wouldn't bother, unless the power on surge is a problem, as it's just something else to give potential problems.

I had it wired blue and brown to mains 240v, grey and violet joined on the input side. On the output side orange and red to the rectifier, yellow and black joined. This was a dual 25v output core.

Thanks to the Legend that is Dean I got a stepper to move last night - woohoo!

Did a little more work, haven't finished these side plates yet but thought I'd show where I'm up to.... they still need milling on the underside but I haven't quite decided how I'm going to do that...
