Another very happy customer here. Just received the relay output board for my "legacy" Acorn.

Re: Acorn relay board

I'm 99%+ sure that the ratings given are for MAXIMUM voltage and current. As cncsnw was saying, DC is harder on relay contacts than AC, so the DC rating is only 30 volts (maximum), while the AC is 240 volts (maximum). Your 350 watt 110 volt motor will draw around 3 amps of current. 3 amps and 110 vo...

Re: Heartbeat

There are a couple of videos where @cnckeith talks about the "heartbeat" LED on the Acorn, and how useful it is to verify that all is well with the board. I was a bit confused about what exactly he was talking about when he mentioned it in the setting-up video. My hope was that, being so u...

Re: Question about Gcode "grammar"

Arf! I'll give it a try on my next project.

Meantime, any word on the DOS-like vs GUI file menu screens?

Re: Heartbeat

Thanks, Kieth! Just for funzies, I'm planning to run a fiber optic from somewhere near the beglebone to (through) the front face of the controller cabinet. I've tried holding the fiber optic near the LED, and I think I can make it work. So I can keep a continuous eye on the reassuring heartbeat. All...

Heartbeat

OK, I've been watching a couple of cnckeith's and Marty's videos about the Acorn. In Keith's video on how to update the software to 4.5, he mentions checking "the heartbeat" several times. He always seems to be looking at the PC screen when he mentions this. But in the Acorn bench test (in...

Re: Question about Gcode "grammar"

Thanks to all for your replies. Question to Marty, regarding something you posted: "Have you read up in Chapter 10 on Intercon? Have you tried the tutorials? John, I think you would really like it since you are doing much hand coding." I've read about Intercon previously, and may yet try i...

Question about Gcode "grammar"

This came about as a side issue on another problem, since solved. My question is in regard to adding parenthetical comments to Gcode. Background: (1) I bought a (FANTASTICALLY well set up! Thanks, Marty) DynaMyte DM2400 CNC milling machine from Marty a bit over a year ago. I was initially interested...
