I found a steel shop in Tualitin with a laser that can cut 1" steel.

I live in Woodburn, OR about 30 miles south of Portland on I-5.

Alan

If anyone is interested, I just posted my 20" Woodtek Disc sander and my G1071 Grizzly Oscillating spindle sander on the Portland craigslist. These are great tools for anyone interested in doing some...

Mike,
:)
Sorry for the delay. I am a slow thinker:). I just sent you a couple replies.

Alan

When people talk about EMC running closed loop they are talking about EMC reading the encoders and making decisions based on the encoder feedback. So, for example, when you use Gecko servo drives...

Peter,

I really don't know, but I would try going back to the beginning and retuning the drive starting on pg 45. I looks almost like a jump to catch up with something.

What kind of encoder are...

You say it is not stalling, but that is the obvious thing that appears to be happening. You are running a 24v supply. That may be all that your driver will handle but it is probably not optimum...

I just finished posting a number of classifieds for a bunch of Thomson linear bearing items.

If you are getting ready to start a router, you might find something useful. I have attached a couple...

ameinert,

I wasn't even thinking that you were trying to mislead anyone. I just wanted to make sure that you had thought thru the issues before spending a lot of time constructing something only...

Maybe we should have an FAQ with some starting guidelines for people. Like what is the basic calculation for necessary Z travel?

Minimum Z travel should be the distance from spindle end when the...

That's fine. In my book that counts as part of clearing the 22". But if you build a gantry that only clears the lowest part of your machining surface by 4", then have 22" of travel, it is wasted.

I see a lot of people trying to achieve long Z travels without fully analyzing their problem. It doesn't do any good to have 22" of Z travel if the bottom of your gantry and/or the bottom of your...

I don't see a power supply in the kit????

Thanks Pete, that answered my questions, I hope it helps gombault.

I haven't even ordered my 7i33TA yet but the info I got in another thread was that (for drive0) I should hook the +-10v to AOUT0 (pin 10) and the other wire to gnd (pin11). Maybe Peter Wallace can...

I have a CandCNC mini-IO BOB in my CNC Lathe Controller and had another in my CNC router that I sold. I have only had one problem with the two of them and Tom sent me a replacement BOB right away...

Right, the 7i33 has an EnableOut and a corresponding /EnableIn for each drive. I was not trying to document all of the connections that need to be made. I was just trying to figure out how I was...

Thanks, Al.

Yeah, that's why I made the comment (anemic) power supply.

I found the connectors at Mouser also. The housings (plastic) are slightly more expensive at Mouser than Digikey (3 for...

Thanks Al,

OK, on the 30A8T
Pin 1 is +10v/3mA output
Pin 2 is signal gnd
Pin 3 is -10v/3mA output
Pin 4 is +15v(max) +Ref Input
Pin 5 is -15v(max) -Ref Input

Lets just take the...

I would code using a subroutine, then pass the subroutine a x, y start point and change the g55 offset inside the subroutine then cut the part. You could call the subroutine from inside a do-while...

OK, I have another question. It appears from the manual for the 30A8T that it expects 0 to +10v on one pin and -10v to 0 on another pin. The 7i33 and 7i48 have a single output pin for each amp that...

The Intel 510 is 1.6gHz and has a 26pin header for the parallel port while the 525 is 1.8gHz and has a DB-25 for the parallel port. There are some bugs in the 510 bios that are fixed in the 525 bios...

I have a Intel D525MW mb running Ubuntu 10.04 with EMC2. The SSD boots up fast and quiet.

Alan

Thanks for the link. That is what I have been looking for.

I have a 7i43 and two 7i42TA daughter cards to which I can wire the encoders. I may go ahead and build one of these to try it out. I...

Yes, but I don't currently have anything to generate +-10v, while I do have something to generate PWM/Dir. Hence the questions:
Is there a simple circuit to convert PWM/Dir to +-10v output?

Or am...

Not a serial cable -- a parallel cable.

I use EMC2 which closes the loop so that is not a problem.

Take a look at these. I converted it using PCB-GCode.

Alan

I picked up some used Advanced Motion Control 30A8T Controllers (Brush Type PWM Servo Amplifier). They require a +-10v analog signal.

Has anyone used these?

Is there a simple circuit to...
