Hi Guys,
Thank You for all of your suggestions re my Axis problem.
This last week I went back with as much determination that I could muster to solve my Axis problem. I first tried and re tried...

Thanks very much for that Roger. I will try everything you have suggested. I have been soooooooooooooooooo frustrated I have walked away from it for a while to gather my thoughts. But I will...

Hi,
I have tried most things suggested. There seems to be more things going wrong than I am fixing. I am starting to look at Computer and software. It looks as though it is going to take a long...

Thanks guys, I really appreciate your suggestions. I will try them all. If I can't get it to behave I think I'll rewire the Z Axis stepper motor from BOB to motor.
Thanks again everyone.

Mate, all the trials that I have run has been without the spindle running. It is a 3KW spindle which produces a lot of noise. All cables running to and from the VFD are heavily insulated and mains...

Thanks Roger I'll try that and report back.

Hi Mate,
I have checked the distance moved, it is correct. I will play with the dip switches on the motor drivers and slow down the Acce and velocity in Mach3 to see if that helps.

Thanks Roger,
I thought of grub screws, but, the problem is that the bit cuts deeper into the wood so would require more grip, which sort of rules out loose grub screws.
All other axis are OK. I...

When it is supposed to be cutting at a depth of 3mm, it is actually cutting 15mm deep.

Hi Steve,
The Z axis ends up lower. Mach 3 programme tells me it should be at a depth of 3mm but the read out is showing the actual depth of the bit is say 15mm.
It never done this in the 10 years...

Hi Jeff,
Thanks for your quick reply. I have to go away for a couple of days, but will post a video as soon as I get back. Thanks again.

Hi,
I am nearly going around the bend.
Have a self build CNC and all of a sudden I have a problem with the Z axis gaining steps for NO apparent reason.I have tried anything I can think of to fix...

Hi Andrew,
Many thanks for your suggestion. Here is some more info.
Yes, it is a DIY router. But not cobbled from cheapest parts available. Most of the hardware was purchased from Probotix America....

Hi,
I hope someone can help.
My X Axis has decided to stop for a while whilst cutting a job. The program keeps going but the stepper stops. When it starts again, which it does it has lost a couple...

Hi Mate,
The Z Axis is a 4HP spindle motor. 4 pairs or 8 wired. I am unable to send you photos within this forum, but if you were to send me your email address I will enclose photos. I built my CNC...

Thanks mate,
I will certainly check out the wiring situation. The Z axis is driven by a step spindle (4HP) and so far only drifts upwards. I have slowed down the stepper to see if that helps. I will...

Thanks Andrew,
I think you are spot on. I will try that to day.

Many thanks again

Terry

Thanks Mate,
I was a bit scant with my info. I only loose steps from the Z axis. I wonder if it because I was running the CNC too fast.I will check the couplings.
Thanks mate for your reply...

Hi Everybody,
Does anybody know why a CNC router loses steps, and how can I fix the problem, I am running Aspire V4 and Mach 3.

Kindest regards

Terry

Thanks for that mate. I have just tried your suggestion. I slowed the other two axis down as well.......Result was no difference, still gaining steps. Any other suggestions please, I'm getting...

I'm gaining steps on the Z drive. Can anyone help me to correct this problem please?

Help,

Can anyone help me. My CNC Router is gaining steps on the Z axis. This has happened all of a sudden. I can't explain why. Howe can I fix the problem?

Joe,
Many thanks, I have really appreciated your advice. Like you I also work in imperial and metric only when I have to.
At 63 yo and attempting my first CNC Router it is really taxing my aging...

Many thanks for that.
So from what I hear you saying I would be better off with either single start or 2 start because the length of my x axis is 1500mm and y axis is 1100mm. This would discount...

Hi Guys,
I'm a newbie.

What in the hell is, single,2 & 5 start rod. Which one do I buy?

Thanks Guys

Hi Guys,
I'm a newbie. I have been saucing out the hardware that I require to build my first CNC Router.
I am confused regarding Acme square threaded rod. Can someone please explain to me what...
