I want to use UCCNC for my new CNCRP build but the ESS does not support UCCNC. I read on this forum that the UC300 is a good substitute and I am wondering how switching the boards out would work.

Config:

Plug and Play NEMA 23 CNC Control System:
Additional Motor Drive: +1 [5th-Drive Upgrade]
Cable configuration: (1) 12' and (3) 20' cables [recommended for 4'x'2' or 4'x4' machines]
Motor Shaft Diameter: 3/8" (Low Inductance 420 oz-in)

Pepperl + Fuchs Proximity Sensor Kit:
Sensor Configuration: Homing/Limit 6 Sensor Kit (4'x4' machines, or smaller)

Auto Z and Corner Finding Touch Plate

2.2 kW Plug and Play Spindle / VFD System
Compatibility Option: CRP800 (Standard)

Was the power up bug ever fixed?

[ger21]

Are you talking about the issue with the spindle starting during power up?
It's not really a bug.
The UC300ETH pin states are different than the ESS, so when you use a breakout board designed for the ESS, you run into this issue.
I was originally using an MB2 breakout board, designed for the ESS. When I switched to a UB-1 breakout board, designed for the UC300ETH, I no longer had this issue.

And as was mentioned in that thread, you shouldn't have power to your machine until UCCNC is running.

Is there any sort of walkthrough for dummies for switching from the ESS to the UC300? I also have a CNCRP plug and play setup (NEMA34 if it matters) but am interested in experimenting with UCCNC - would give it a go to switch out the controller but would need some documentation...I'm moderately technical, but am not at all familiar with the innards of the CNCRP 'black box' I've purchased (and has been running great).

Do you know where I can find a pinout for the conversion? I found a pinout for the ESS to UC300 swap but I'm not sure how to switch breakout boards.

I'm not aware of any other info on making the conversion. You should be able to just unplug the breakout board from the ESS and plug it into the UC300ETH.

I mean switching from the MB2 to the UB1.

[ger21]

The UB-1 manual has all the info you should need. If you go that route, you basically scrap everything in the plug and play kit except the drives and power supply, and wire everything to the UB-1.

How should I connect my drives to the UB-1? There are 3 options and I'm not sure of the differences. Are the included sensors NPN or PNP? And how do I wire the sensors (the manual does not mention the slaved axis)? How do you wire the charge pump and safety interlock in your setup?

[ger21]

I don't really know anything about your existing components, so I don't know how they should be connected.

Oh. So is there no way to resolve the Spindle power-on bug without gutting the entirety of the CNCRouterParts PNP kit? That's sad.

(4) All digital CRP5056 drivers, pre-wired to power terminals, motor plugs, and logic board.
CRP550 "bridge" board that plugs directly into the four drivers, with support for a 5th motor driver.
CRP560 panel-mounted IO breakout board, featuring (3) 15A relays, (8) 12V powered M12 ports for home switches or general input signals (proximity switches sold separately), and on-board 0-10V analog output for spindle speed control.
Ethernet Smoothstepper - included standard for expanded I/O, faster processing speed, and better comparability with modern computers/operating-systems!

This are the parts in the plug and play kit. I can't find manuals for any of the CRP components so I'm guessing they are proprietary?

Again, I don't know anything about your current system, so I don't know the answer. And again, imo, it's not a bug. I don't have any issue with the spindle coming on when I turn on my machine. And I don't think other UCCNC users do either. If the hardware you are using results in the spindle turning on when power is applied, add a simple relay in the chain so that it prevents it from happening until UCCNC is in control.

Yes, their boards are proprietary, and I don't really know anything about them. I'm not an electronics expert, so really can't give you instructions on doing this conversion. But normally, you can just replace the ESS with the UC300ETH.
The other thread I linked to spells out some issues and concerns that the other person mentioned.
