I was thinking that too.  But it is very repeatable, I will need to measure at what distance it starts to fail.

Wasn't sure if there was a max travel when homing or if this was time driven.

Thanks

General Mach Discussion / How do you increase the search travel for DoButton(22)

« on: January 17, 2012, 11:24:31 AM »

Q1:  How do you increase the search travel for DoButton(22) ? 

Q2: Is there a limit of the search Travel ?

My X Axis has 32 inches of travel.  If I use DoButton(22) to home the X, sometimes it stops before reaching Home.  This only happens when I am at the far end of the table.  Any Ideas ?

Thanks

No problem, I hope it works for you.

Yes, we used/saved the PS, Amplifiers and Servos.  Gutted the reset of the stuff.

If my memory is correct, its pin 6 below.  This is how you lock the servo on.   Not sure on the voltage level, could be active low, 5 or 12 VDC.   I sold off this machine several years back.

JH,
    Man that is kinda steep  but quality costs sometimes. I assume these are mostly plug and play right so should be well worth it. Does it come with cabling and whatnot for it as well?  Are those motors coolant proof?  I guess $3300.00 for all three brand new motors and drivers ready to rock on a nice VMC like this will be money in the bank if you ever have a problem with any of them.   It really looks like the biggest difficulty of these conversions is the damn toolchanger huh. Gotta have it but all those sensors and logic settings are gonna be difficult and time consuming I would imagine.  You make this stuff look way too damn easy my friend.   BTW, I had a guy come to my shop today with a Harley Davidson and I tig welded some brackets he broke on his frame that hold the saddlebags and exhaust on. It was pretty cool and I thought of you and your cool Chopper shop while I was working on it. That was the FIRST Harley I have worked on... haha Peace

Pete

Pete,

Only money and free….  once I sell off the old motors and amplifier.  The Tool Changer is not hard, once the hardware is interfaced to Mach3 its all software that can be reused from the BP412 project.

I am glad to see you working on Harleys too

Sounds like they are working out well. I think you may be fine if its anything like my lathe, the motors on that were monstrous, cant remember  the exact specs but they were big.

What kind of accel are you getting out of the axis?
Hood

Hood,

I have installed the X and Z Axis Servos and I am still playing the accelerations and servo tuning parameters.  My Mach3 acceleration has been all over from 30 to 80 in/sec depending on the servo parameters at the time.  I think in the video it was around 80 in/sec.

Do the X and Y need to be the same for the linear interpolation to function correctly?  I wasn't sure about that.  I have always had it the same on my other machines.

Thanks,
JH

The Anilam 1100 Amplifiers are analog.  We were able to get this functional using pixie 100s (Step Dir to Analog Converters)   Pixies are no longer around, but there are other options out there for this.

I have attached some PDFs that I found during my investigation and the pinouts list that I was building.  Hope this helps.

Ive got a 1995 dm4500 w/ a m3 control  i m not sure if it can rigid tap.an or does anyone how to tap in this machine

Contact these guys, they are still supporting it.

Also, this is DM4800 to Mach3 conversion topic, I do not think you will find much information here about your DM4500 machine.

Looks great JH. How do the new motors compare to the originals speed and torque wise. They look smaller but the newer motors can produce more power from a smaller frame size I presume.

John.

John,

The new Servos and stock Servos are not 1:1  The stock ones are rated at 2000W a 17 N/m while the new ones are rated 1000W 9.5 N/m (28.6 N/m peak).  I have demonstrated that I can run them at 1300RPM without an issue and this agrees with the torque/speed chart thus pushing the wattage to ~1400W.  I am also counting on the fact that the engineering that went into the stock design was over designed by at least 25 percent. 

Only time will tell if I have chosen to small of motors for this Machine.  I think I am on target for my intended usage and duty cycle of the machine.
