Semi works with original screenset wont with 2010. Hey this is a funny one! I am using a Chinese BOB because I am a true tightarse and actually dont mind it. I am going to take advice soon (in the next few years) and go for a nice board one day. I have pretty much rebuilt my machine so best I do.
I have decided to control my new spindle with my BOB.... or PC anyway. Bench testing the BOB I have been unable to get the 0-10v output to work. Its the common BOB all the Chinese are selling. Has a 12-24v input, and a 0-10v spindle output. Not sure why it wont work, I reckon it is not a winner to be honest. I have a few of these boards and none of them even give me a volt out of the spindle output. Perhaps I have wired or pinned it incorrectly, I dont know. Its been a sound controller though I will say that. This forum wont let me upload a pic sorry.
What I have found, is I am able to get a 0-5 voltage out of the pin I choose to control the spindle speed. Its linear on what speed I select. So I am going to hook up a Homman (spelling sorry) DC03 to convert that 0-5v to 0-10v - it has a connection to go straight onto the 10k pot input on my HY VFD . Perhaps its actually a PWM singal that is working? Quite plausible given I am getting 0-5v.
But. Playing around with this setup on my table, I have been able to get my BOB spindle relay to work, on/off, no problem with the original Mach 3 screenset. No problem at all. But on the 2010 screenset, same pinouts, it will not. the little LED on the BOB with the 2010 screenset kind of just luminates about 40% brightness, and the relay stays where it is. Its weird, I dont understand how different screensets can do this? Any ideas why?
Actually, if anyone has gotten one of these BOBs to work with the 0-10v output to work I would like to hear about it.
