What is and where does one find Screen4?

Thanks,

Update.  Installed the software onto my PC and it ran perfectly at 1 minute and three seconds.  I looked at my laptop again and realized the driver test fails on the laptop.

Thanks Graham,

I guess it is just my system.  I was working on a laptop that has many processes running at one time.  I will retry the test on a PC when I get home.

Thanks again.

General Mach Discussion / Mach 3 and feedrate

« on: March 12, 2007, 03:11:37 AM »

Hello All,

I downloaded the newest Mach 3 v.2.055 tonight.  While testing it out I realized that the IPM did not correspond to the DRO and the actual time that passed.  Note that I was running the software exactly as downloaded and that it was not hooked up to a machine.  At first it seemed the feedrate was running at half speed (i.e. the feed rate was set at 120IPM but the DRO only read 60 inches after one minute).  I then restarted the program a little later, reviewed settings (I made no changes) and then tried the test again.  At this point the opposite occurred (i.e. the feed rate was set at 120IPM but the DRO reached 120 inches after only 30 seconds).

Am I missing something?  I would think that if I coded the feedrate at 120IPM that it would take one minute (plus or minus a few seconds) to go 120 inches.  The G code I used to test this was very simple G1 X120 F120.

Thanks in advance for your input.

General Mach Discussion / Re: Pulse Coder- Way too many wires!

Hi Darek,

Does Z = Index?

Also, how do the Temp switches work?  Do I use them as emergency stops if the motor gets too hot?

Thanks!

General Mach Discussion / Pulse Coder- Way too many wires!

« on: March 11, 2007, 03:05:14 AM »

Hi all,

So I was tearing my machine apart and strategizing my retrofit today.  Things were going along fine until I took a close look at the wires coming from the pulse coder.  I was expecting anywhere from 4 to 8 wires depending on what type of pulse coder I have (single-ended or differential encoder).  However, there were 20 plus wires!  I am hoping one of you guys could take a look at the pics I posted below and let me know what I am dealing with and how I should handle these various wires.  Thanks much!

Motor:  Fanuc Model 0 DC Brush motor
Encoder: 2500 Pulse Count
Excit. Perm. Magnet
RPM: 2000
Volts: 56V
Cont Amps at Stall: 12A
Torque at Stall: 2.7Nm

Hello Ardor,

I think I read somewhere that you need to fully uninstall prior versions of mach 3 prior to reinstalling the newest version or its possible you will have glitches.  I have source amnesia as to where I read that but you may want to give it a try.

General Mach Discussion / Re: Minimum PC hardware required?

« on: March 05, 2007, 08:09:20 PM »

Hello BobL,

I believe the Mach 3 manual states that a minimum 1Ghz machine is recommended if you are running the Kernel speed at 25k.  I think you may need a faster machine for a higher kernel speed (35k or 45k).  I believe there are more specific specs in the manual for ram etc.

General Mach Discussion / Re: Is there a difference between a pulse coder versus quadrature encoder?

« on: February 24, 2007, 01:22:36 PM »

Thanks Darek,

I have a few more questions and thanks so much for your insight thus far.

1.  Is this the type of F to V board I will need:  http://www.eidusa.com/Interface_Boards_F_to_V.htm

2.  Were the rest of my assumptions in my prior post correct?

3.  If the I and D functions are useless, is the p100 the way to go?  Will the board still work even though it won't handle the encoder signal?  Is there an alternative board or combination of boards to use?

4.  Suppose I was ready to junk the entire control system.  Meaning, I will only have the machine, motors, and external devices (spindle motor, coolant, etc).  What system would you reccommend I use?  I don't want to break the bank but I want a system that is appropriate for my machine.  Let me know if you need additional specs.

5.  The machine is currently using 3 phase.  If  changing the controller setup, would it remain three phase or is that dictated by the motors?

Thanks so much.

David
