Older Shopbot desktop build
Posted: Wed Apr 24, 2024 3:29 pm
Hello,
I am exploring the idea of updating my older Shopbot desktop to an Acorn controller. I will post pictures as I go.
Motivation: Flexibility of more industry standard/open design. This will allow me flexibility for customization and also I will be learning on something more universal. Note I am a pure hobbiest and do not push the machine in terms of performance. It will be a learning curve for me but looks possible.
Current machine: Stock Shopbot 24/18 Desktop. (note this is not the newer Desktop, nor the Desktop max.
Current electronics and drives: stock shopbot
Current software: SB3 version 3.8.5 (running on a windows 95 computer that amazingly has been working fine for years)
Spindle: stock 800W spindle (HSD, 220V, 200Hz)
Current VFD: Delta VFD007S11B (110v input)
Steppers: Ametek K57M4Y-007, C1523
Indexer: I do have, and want to continue using an indexer
Note the VFD and spindle speed is controlled manually not from the software.
First upgrade capability I would like to enable is to control the spindle speed via the software.
Once that is working I would like to consider adding ATC. (either pneumatic or rapidchange atc) - as a second phase upgrade
From what I have learned so far, the AcornCNC controller should suffice for basic operation.
I would couple this with a Leadshine 4660 4 channel stepper driver
And a DuraPulse GS20 VFD for the spindle
I can use the original power supply
I am only getting started so welcome any insights, reference links, or criticisms.
Thank you
