Iā€™m using Version 1.4.11 and even though I have my Z-touch puck dimension set up in the settings, it does not comp for the thickness of the probe. When I go to run my program, my tool is above the part by about the thickness of the probe. I can touch off manually with a piece of paper and everything runs as it should. What am I missing here? ---

@DIJANAB89 A belated welcome to the group, Dee. I apologize for the delay. What machine do you have? Youā€™ve put your post in the SLB category. You are running a Sienci SLB controller, correct? Are you using the standard Sienci touchplate? ---

I see. My post is actually in the wrong area. I misunderstood what Super Long board means. No Iā€™m not running this controller. Iā€™m just running g-sender from my PC to my anolex cnc. Can you send me the link for the correct board please? ---

@DIJANAB89 Iā€™ve moved your topic, Dee. I looked on the anolex site but I could find no specs on the touchplate. Do you have a link ---

Thanks for the help. Itā€™s one like this- [https://a.co/d/9Q234FU](https://a.co/d/9Q234FU) ---

@DIJANAB89 I donā€™t see any dimension specs. No worries. I assume that you measured it with a caliper, correct? In gSender, you have selected ā€œz probeā€ from the ā€œtouchplate typeā€ drop down menu, correct? ---

Correct. The probe measures .762 or 19.35 mm. I set that in the probe height offset, use the M6 standard re-zero tool change wizard, and it does not compensate for the height of the probe. If i touch off using the paper method itā€™s fine. ---

@DIJANAB89 it might be worth re-trying your process on a newer gSender version like the one we just released yesterday 1.5.5 since we did some more overhauling to probing which might fix your issue ---
