Hi Gerry,
Yes I did try a damper, I made a tunable damper with a rubber mounted damper weight that could be relaxed of stiffened up via a tension adjustment.
Unfortunately all it did was make it...

Thanks to those who have posted.
More info re why the Poll
A bit more of an explanation is now evident after more research. A friend had loaned me a couple of old G201's to try on my machine to see...

After having trouble with slow speed steeping problems on my DIY CNC for some months when stepping any more than 1/2 steps I'm interested to know
what others are stepping at and if they also had...

Thanks guys,
It's a 4 mm pitch and so I have the driver set to 800 steps per rev so I'll give the next step up to 1600 steps per rev a go and see how it performs.
I did try this prior to fitting...

Hi all,
I still have issues with the X axis with rough stepping at different speeds during a cutting run.
This is a dummy run to show the noisy stepping as it transitions through a run and this can...

Hi Stutank,
Nice to know there are some other locals around to talk to. I see you've been on here for a while.
I now have my router running well after adding an Ethernet Smoothstepper so now just...

Ah yes I see, I also have that illness with another hobby, that of astronomy.
Bigger is always better. :)
And now it's cnc as well.

Interesting comment there Roger. To coin a phrase of a well known political lady (please explain)

Hi all,
Just setup a new ESS on my laptop, moved over from PC with LPT1 to BOB and the new setup on the Laptop isn't giving me any keyboard jogging.
Is this normal with the ESS or is there a...

Hi Sean,
No mate, I have made spinners and a few other lures but none with the bibs like what you're doing.
The Shapeoko looks like a reasonable unit and would most likely lend itself quite well to...

Building is great if you like to make things and can save you a few bucks, depends a bit on how soon you want to get up and running.
I recently built my own 3 axis, see my blog HERE
This took me...

Thanks John,
Ran it again today without issues so I did a job for the wife that she has been waiting for, the daughter had broken one half of a patchwork quilt templeate she borrowed and I had the...

Well the problem returned with a vengeance so after some more stuffing around and the addition of a second printer port PCI card with a similar result I spat the dummy and removed said computer and...

Yes and no James, this is from a selection of sample Gcode/CRV file from the Vectric Home page and it's really good to use as a test for the machine but I have almost made enough of them for a...

Thanks James I think you may have struck upon something with the possible port corrosion as like you say it is an old PC that has sat around with nothing connected to the printer port.
Checked it...

Well my good luck ran out today and the unreliability and missing steps has crept back in again and quite badly at times on all three axis. Had a play with the motor tuning but no joy.
Some code I...

It is a switching supply and I had noticed the possibility of some harmonics creeping in as my motor speed is beeing set in mm per min small changes of say 30-50mm min would see the motors become...

Thanks for help and suggestions of ways to remedy my problems. Some of these may be looked at again if I have more trouble.

Below is a copy of the post I put up on my build blog. DIY CNC Router |...

Ah yes, commonly known in the automotive business as a harmonic balancer, (a damper). I'm a mechanic you see.
Thanks for that and as I do have dual shaft motors I may try the simple fly wheel for a...

Thanks John and Gerry,
The USB power is from a plug pack not a USB port but I will check its current limit to make sure it can supply enough.
The driver test is not as smooth and flat as it could...

Thanks for the comments Ian.
I have yet to check the bios setting for LPT 1 but I cant recall altering the settings although it is an old PC and I may have changed things some time back.
No...

A couple of notes re the BOB.
None of the limit switch connections functioned or the Estop either, tried active high and active low, not sure why they didn't work.
All the pins and ports were...

Hi all.
Recently finished, well almost finished CNC router, see my Build Blog HERE was travelling a bit slow, not what you would call rapids at 500 mm/min.
My initial setup was with the ubiquitus...

Thanks, I have a bit to go yet on the construction side of things and then the wiring etc so nice to know that you're willing to help.. Will let you know when I'm getting close to running. Still...

Hi Alan,
Not wishing to hijack (maybe shouldn't use that word, big brother is watching) MecAut's thread here but as I'm on my first build I'm interested in talking about Mach3 setups before I run my...

Hi,
I'm not far from Geelong and have just started a diy desktop router build.
If you are still looking to share info checkout my web page and blog for the build.
