My Grizzly G0619 mill

I just got finished shooting video of the repairs to my stepper drivers. The Z axis was the most tricky
it turned out I had burned the 270 ohm resistor for the optoisolator the resistor had a value of
45-50Kohm yikes. Once I replaced that the driver worked fine. I had also purchased a new KL8060E.
Since I now have a spare stepper driver I will install it as well so if I want to use one in the future I
can drive a 4th axis.

Well editing took longer then expected. Is it just me or has the internet in general been
really slow today. I will have part 2 out later this week in the meantime here is part 1.

tommylight  I actually got the Z drive working. It turned out to be a cooked current limit resistor
inline with the optoisolator.( it specs at 270 ohm but it tested at 45-50 Kohm )
though I will admit I never used the ENA. circuit with the mach 3 controller so it is possible
that it never worked on the Z drive anyway.
In PT.2 I don't show myself actually doing the repair too simple and boring
Plus dealing with matters concerning hurricane Ian. LOL . I do however show that the drive is
once again operational.

And here is part 2.

Boy time flies. It's hard to believe it's 2023 already. I had taken about a month to upgrade my
Anodizing line to make it more user friendly and more automatic. I can now get to work (5:30am) and
the tanks are either already at temp. or will be so when it's needed. On the G0619 I built most of
the external wiring . So I figured the next step was to cut out the I.O. plates . Unfortunately I ran into
an issue with my Autodesk Fusion 360 software. I sent a couple of DXF files to a company that does
water jet / laser cutting only to have the finished job be twice the size I had specd ( not their fault ).
Frustrating to say the least , more so at my self for not catching it and fixing it before I had sent it out.
Oh well it's always something.

That sucks. I always send a pdf drawing of the part with any DXFs we send out.
It might have let you blame them and not wear the recut!
Also the F360 DXF workflow I use is to:
1. Create a flat pattern and flatten it If sheetmetal
2. Add a new sketch on the flat pattern  or surface of the part if not sheetmetal
3. Now in the tree, right click the sketch and save as DXF
4. Create a sketch showing outer dimensions and dimensions to any fold lines
5. send the pdf and dxf to supplier..

  I figured I would post some pics. for people to get a laugh at. The one I set a DB37 connector on just to
give a sense of scale compared to the cutout it was intended for . The other I put an Mpg Pendant on
to again show the over-sized scale.

Ouch! and you paid money for that?
And it does not even seem to be a metric thing!
Send a dimensioned drawing with it next time! Or build a plasma table!
