Chris, here's a link to the Haas control manuals. They are pretty well written and mostly Fanuc compatible. http://www.haascnc.com/custserv_updates.asp#manualupd http://www.haascnc.com/customer_service/manual/vmc/96-8000.pdf http://www.haascnc.com/customer_service/manual/lathe/96-8700.pdf When an

Re: [Emc-users] Emc-users Digest, Vol 16, Issue 11

Gentlemen, I will try to explain how the fanuc control uses the G28 command and then later I will look up the command in a fanuc manual to try to corroborate my explanation. Steve's description/quotation is accurate. The G28 command is in essense a two part command. The axis departure c

Re: [Emc-users] G28 behavour

Hi Greg, et al Ah! Now the intermediate point make sense. As for an alarm with G28... I wouldn't know. I can comment that with G54 and G53 co-incident a G53Z0 does not cause an error when tool length offset is active. Because of this I've gotten in the habit of raising the spindle and then

John- If you do use the AD steppers would you post your results here? I've got a small CNC router project scheduled for early next year and was planning on using those steppers. Thanks, Javid Butler - Original Message - From: "John Thornton" <[EMAIL PROTECTED]> To: Sent: Saturday, A

Re: [Emc-users] G28 return to home

Hi Stuart, can you find for us a reference that explains how G28 typically works on non-EMC controls? If they all work the same except for EMC, we could talk about breaking with ngc for this. In particular I want to know how it should behave when in G90 mode and all axes are specified in G90 mo

Hi John First, if you haven't already, you should read the "step motor basics" document here . I haven't used the Automation Direct hardware, but the stepper motors should be pretty standard. They're 3.1V motors, so you should be using a

Hi Roger What would be the advantage of the Gecko drive? Price is not an issue as it's only a few bucks cheaper. If I had any issues with the "system" with mix and match componets it could get sticky... as to who to call for support. Thanks for your input John > > I haven't used the Automati

Re: [Emc-users] Automation Direct Steppers

I haven't used the Automation Direct steppers or drives but if it were me, I would buy the Automation Direct stepper motors and Gecko drives. Here's a Gecko drive rated up to 7A at up to 80V with 10 micro-step for $134. http://www.geckodrive.com/product.cfm?pid=10 Last time I looked, there were
