Z depth of cut issue

I have a question for ESTLcam users. I made the setup just like the pictures shown on the website. My cnc controller units was set as inches so i changed it to Millimeters as shown in the pictures. I tried to make the cut for my strut rails but the holes were drilling really close to each other in Y direction, X direction seemed just fine. So i changed the CNC controller back to inches which helped in drilling the holes far enough on the Y axis.

But now im having issues with my Z axis. I have set my z depth per pass on the tools tab to be 2mm and the code shows it is going down to -2.0 in z direction but in actual its completely cutting through my 3/16 hardboard piece in the first single pass. I cut the program right after to avoid any problems .
Do i need to check my lead screw setting? I bought the leadscrew from the V1 store with the LR4 kit.

Can anyone guide me in a specific direction? I’m looking around on forums too but any suggestions is much appreciated.

Im talking for LR4

Can you jog z up/down a set amount in the software and compare that to measured movement?

It really depends on the video you are talking about, there are a lot… You need to set the steps so it fits your hardware.

you may have something off: X/Y steps must be the same in our machines, please check the theethed pulleys and idlers to be the same on both the X and Y axis. your y axis needs to be calibrated for your actual threaded rod on the z axis. did you sourced them your self or was from a @vicious1 Parts kit?

@Dreyfus I am planning to do that today once i get home from work and also check my setting to see if something is off.

@CesarH I did buy every part of the build from the V1 website.

Then you must revise your grub screws for the y and z axis frist,

Do some air cuts with the router off with vac on/off, check drivers temps etc. If you dont loose z steps with the router off then it is easier tobegin troubleshooting your build

But one thing at the time start first the y axis (grubscrews loose would be the first thing to look at -with stock firmware)

@Tokoloshe i saw one which showed the person bought an off market lead screw and had to adjust the setting to match the lead screw. Though my items are all bought from @vicious1 but im going to verify if they are set the same.

They should be the same if you sourced directly from v1 store (as a kit) unless you bought the other one with different thread individually

Take a step back and lets troubleshoot your issues one by one. Please start with the y axis. Check if you have something loose

Did you sourced everything of a kit or bought them individually from the store? The correct spec is a 4 start screw, confirm that
So you can troubleshoot the z axis, are you getting binding?
Verify your coupler is tight in the motor shaft and the leadscrew (with blue loctite)

Are you setting your zaxis 0 over the top of your material?

@CesarH so i had purchased the LR3 kit in 2023 from V1 engineering website which i never got to building. Then when LR4 got released i just purchased the upgrade kit again from V1 engineering and use all the LR3 hardware with the LR4. So unless anything changed between then now i think i should be stock.

Let me know if I should be doing anything else.

I did do the square test where the machine automatically goes to the 4 points, does a point poke into the table and moves to the next point. Its from the video which @DougJoseph posted. And the machine ran completely fine and i was able to square it.

@CesarH I can check on the coupler tonight and yes I’m setting the Z zero on top of the raw material.

as i said, fix on axle at the time. start by your Y axis, then move to the z axis.
