As I stated in an earlier post, I bought an Isel router of late 1980's vintage ( I think)
I bought it from a former employer for the princely sum of (equivalent of) 350 US dollars.
I was looking for a desktop CNC to play around on. Somehow, in the years since I left the sellers employment, I forgotten the size of this machine. I just drove about 550 miles to collect it. Boy, it is MUCH bigger than I remember :-)
The milled area on the bed is about 500 x 960mm (20 x 38.5 inch). The router came with a couple of spindles: 1x 400W Atlas Copco (Milwaukee) 30 000 rpm fixed speed, and 1x virtually unused Kress 900W Variable speed.
When I first thought of this router, I was planning to use it as a base for a semi DIY machine. But everything is in such a good condition, that I am going to keep it pretty much as it is, with only a wee bit of modernizing. I hope.....
Initial plans was to use a Gecko 540, but I really want USBCNC.......
Now, for the Million Dollar Question: The router came with a Techno C116 controller. All neat in a strong aluminium box, and lots of different DC outputs. Can I use the stepper drivers in this controller, and simply hook them up to a USBCNC breakout board? According to an online PDF document, the drivers output 44V / 3.6 A. This is quoted from the literature:
STEPPER AMPLIFIERS
Each Stepper Motor Amplifier (model HL1100M313202) can produce up to 3.6A at 44V
Total fault protection against:
Short circuit across phases
Short circuit to ground
Over / under voltage
Overtemperature
READY TO
USE OUT OF
THE BOX!!!
Will it work?? (Connecting a more modern breakout board to the C116's "HL1100M31320" stepper drivers? If not, I will have to strip out all but the power supply, and replace with a suitable BOB / Stepper driver combo or G540. Anyone done something similar?
PS. I searched the net, but cannot find any info on this size router from Isel. Anybody have any more info, i.e what model number, how much holding torque on the steppers etc? I'm thinking at 44V and 3.3A per phase the steppers are likely about 300 oz??
