SBRP - that's the first time I've heard that name for phenolic. Got it. Thanks.
Your build is phenomenal. Well done.

Concerning a new VFD and MODBUS: I just recently set up a Hitachi WJ200 on the bench. I initially used 0-10v analog signal to control speed but the RPM drifted around somewhat due to electrical noise. It wasn't bad but I wanted to experiment with a digital solution. I was leaning towards MODBUS but not with much enthusiasm; Lots of configuring, several different components, driver's etc. Fortunately the Hitachi has a pulse stream input for speed control. I set up my spindle control in UCCNC to use step and direction output, connected the pulse stream input of the VFD to an axis output on my BOB and a little tuning later had it working very well. 2 wires, no driver's, no adapters and no RPM drift. Just a suggestion.

Thanks, I'll see if I can find out whether or not the pokeys57cnc can do that... certainly a good option to consider.

great work very nice , what motor mounts are you using?

[Zeeflyboy]

Cheers. They are MBA12-C mounts with FK12 bearing blocks and matching FF12 at the other end.

Well, wasn't needed at work today so thought I'd be productive!

Machined one set of wings:

Initial setup for drilling/milling




Fastened down with m6 bolts:




I totally love adaptive clearing on fusion 360:




flipped over and machined on second side:




finished parts:




And some fitted pics:






I've ordered a new spindle, mine is definitely not quite happy and I'm concerned that soon it may start causing actual problems. There goes next months budget

Looking good there, keep it up.

I'm also getting into F360 and it has not disappointed me yet. I can't see myself going back to Vectric Cut2D, unless some very simple job comes up.

When you flip the part to machine the other side how are you aligning it? Looks like you are using the profile witness mark in the sacrificial board and aligning by eye?

[Zeeflyboy]

tah!

Yeah I love fusion, it's absolutely brilliant to me - the modelling is fantastic but the machining side is extremely powerful and well-featured imo, and being able to jump straight from modelling into machining, back again to tweak something and then just having to re-generate the tool path to get the updated tool path is brill.

Flipping the parts varies between the parts, I use dowel pins or the bolt holes, and yes the interior witness line is very useful for checking everything is perfect when just using the bolt holes for alignment if you are careful.
