Well, with the working comp... I was able to do this.

I am hoping the new Spindle would fix the noise issue of the router, as you can hear in the video...

I gave up!

I fixed my other PC, full size tower.  2.4ghz, 1.3gb ram, 128mb graphic... and it work great.  I was able to run 35,000hz or even higher.... Was able to run maximum speed without losing position. 

I am now positive it's the power supply, as adding more hardware made the problem worse.

Tweakie, running the machine slower than it can is avoiding the problem.. not solving it...


As for the driver test... I don't quite understand how to ready the result?  What's consider good and what's consider bad, what are you suppose to look for in the test?

Well, I guess I have to give up... I pull a Power Supply from my old CPU which is a ATX... thought it would work... all the plug fit.  but the damn IBM power supply is unique or something... when I plug my other PS in... it will not power on.


I guess I can go back to my other old comp and have to use that for now.  I am afraid of buying another computer and it freaken don't work.  However, I have start to notice a problem running it with the old comp yesterday.  For some weird reason, running 2500mm-3000mm in the Motor Tune window and main window it's fine.  But when running a Gcode file...   It loses position.... I believe I did not hear the stepper stall or losing step.  But Mach3 totally lost it and the cut miss like 10-30mm of gap.

If I run at about 1000-1500mm/m, then it seem fine.

Well... my friend let me borrow a PCIe 256mb graphic card and try it out.... it wouldn't turn on display... So I went out and bought a new 1gb geforce today... wouldn't work either... So I spend hours searching online finally modify some pin on the card and got it to work perfect.

Guess what?  Didn't help one bit... son of aaaaaa..... gez.  Anyway. I am going nut.  Here's the funny part... NOW even in Motor Tunning, it jitter and studder just as much?   What the fffff???

Only think I can think of is the 225watts power supply... Anyone think this could be a issue?  More powerful graphic card pull more power and made it worse?

Hi Eric,

The Dell you're using, is it the Small Compact one or the standard size PC?  I first was looking at the Dell Optiplex... found one on craiglist for a good price.  But when I call the owner he no longer have it... and he said he have a IBM with better specification and for only 10.00 more... So I went a head and bought it... but didn't know it give me this much of headache.

What's the specs for your Dell Optiplex?

Thanks for the information guys. I got the same problem here.

Can you please let us know what exactly is your problem?  your motor run smooth under Motor Tune but not at main window?


FYI... i tried the new pci adapter paralle card on the IBM computer just for the heck of it... same problem...

Well.. I went to Frys Electronics and pick up a PCI paralle adapter just so I can try my home office desktop with a Built in delicated graphic card...

128mb delicated and 326mb shared...

It worked.

So... I am now 95% sure it's the shared graphic card in the IBM that's causing the problem.

errrr... i guess now I need to buy a cheepo graphic card.

Darn it...   Who could believe a system like this isn't capable of running a CNC driver?  This is too bad, as it's a fast small desktop that would had fit so nicely to my work shop.

I wish I could confirm it's indeed that it need a dedicated graphic card and it will work... I can buy one for 25.00, I would hate to buy it then it will not work... then this computer is useless + a 25.00 graphic card...


Tweakie, are you sure about the Motor Tuning page vs the main Window, the main window require more graphic?  You don't think 200mb shared graphic is not enough?  I thought it would... since the old Dell only have 64mb dedicated graphic card.  Under the TASK window, the system is only showing 200mb of ram being use, and 750mb ram available... .

Hi Tweakie,

I have went into BIOS and increase the amount of shared memory of the graphic card from 128 to 256mb.  However this not fix a thing.

I did do all of the Window Optimize (except the ACPI one)... This did not help either.  Before the Frequency only fluctuate 50-100... After I did the remove of ACPI and put it in Standard PC... .The frequency now are going from 24,000 to 60, 20, then back to 25,000.

This is now officially getting me go to nut.
