Hi guys, This is a cross-post from the mach2 group so if you've already read it... Been trying to set up our gantry machine here all day. Same problem has...
I would recoomend that you start out with some easy to configure software such as KCAM. It is very very easy to configure and get working. Once you have all...
Hi, Make sure the IDC26 cable is seated fully. Make sure the stepper motors wires are all firmly and soundly connected. Does this happen with all axes? Jeff ...
Hi Ray, Is the torque low as well? It sounds like you have lost one phase. Turn off the power and disconnect one phase. Turn on and try the motor. Does it run...
Keith, this is exactly what happens with the motor wired wrong. They seem ok, but dither each way. You don't say how you have them wired. You may have 2 coils...
Well, I think we traced the problem down. I woke up this morning and figured we'd twisted the pairs icorrectly and were getting some spurious direction signals...
... I am effectively doing that here, Keith, by using a microphone cable called star-quad in the trade, which is a 4 wire cable all twisted at once, with a...
Cool. What size motors are you driving? Keith ... From: Gene Heskett To: Xylotex@yahoogroups.com Sent: Tuesday, January 03, 2006 5:25 AM Subject: Re: [Xylotex]...
... Jeffs (Xylotex) 3 pack of 262 oz/in pac-sci's. I'd post a pix of one of them mounted on a micromill but I understand the server nukes attachments. The...
... True, very true, but then I don't know as I'd trust the third pin on the power plugs to be a reliable ground over an extended period of time either. I...
As you've probably seen from my previous posts now, the problem has been solved. The motors were wired correctly as they were 4-wire motors, brand new with...
Yeah, OK. Mine are about the same then. Visually identical except for the labels, I'd say. We left the jumpers at 8th-step and that's enough for us. At 30...
Hi, My take on the single or doubled ended grounding thing: I think the problem with ground loops needs special consideration with signal lines that use a...
Hi Jeff, Whoops - Sorry for the incomplete last post - Finger troubles :( ... Here's an explanation I was given that actually makes sense to me. Avoid ground...
Hi Dave, So now we have three options: single ended grounding, double eneded grounding, and the soft ground (one end soft, one end hard). Maybe your method is...
Hi Dave, One more question. With the soft grounding you mention, would it be appropriate to have the hard ground at the distant end, and the soft ground at...
... So, I must confess, that the discussion is now "outside" the realm where I can actually offer anything constructive (my background is digital systems...
... The one bit of gcode I've whittled out so far, for emc1, was a highly repetitive step & repeat, and had to run the head (z) and y axis back to the starting...
... Well, when we use this cable for microphone cordage, the conductors in it are arranged in a square pattern when looking into the end of the cable. For...
... And that would, in the event of a ground fault, still furnish a suffiently strong signal to trip an NEC spec GFCI breaker. I'd like to see even lower R's,...
... My personal vote goes for the single. In most cases you will have a hard ground by a circuitous route via the 3rd pin on the power plugs anyway. But they...
... Chuckle... I'm in the other camp, Dave, having been old friends with analog (and tubes instead of transistors) for 15+ years before digital turned into...
... And they just announced that 12 of the 13 coal miners trapped about 20 miles from me are alive! Great News(TM). -- Cheers, Gene People having trouble with...
... And, at 2:35 am, an hour ago now, they finally said there was only one survivor & he's not in very good shape. The story is that comm between the rescuers...
OK. Using a 1GHz laptop running Mach2 in Win2k. Outputting through parallel port to Xylotex XS-3525/8S-4 stepper board. Board is powered by Xylotex supplied...
Hi all, Christmas was good to me. Got the money needed to buy some boards and steppers so I may build a CNC router. I know that this site is Xylotex. But would...
