what am I missing here it looks like tools in the rack will not clear the gantry. ![2026-05-22 11.53.21](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/a/ac106b9699d0bda3ec2b9c7a6c69c952c7bebfc9.jpeg) ![2026-05-22 11.53.11](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/b/b786d77707618a3548e72828fb68c9287ddb86d5.jpeg) ---

Hard to tell from your photo. Is the 8020 sitting this high above the sides? The pictures make it look like the 8020 is sitting higher. ![image](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/d/d69bfb2702b2e00da0b0c733d44a1bdeab58c172.png) ---

Additional pictures would be helpful here. My guess is that it’s 20-40mm too high which could indicate that you’ve got part of it mounted in the wrong channel in the 8020 ---

It would not be the first time I assembled incorrectly, but have a look at these and let me know. ![2026-05-22 12.47.02](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/1/1dc9b33805737b40282ca0847738aa52f3e5cf26.jpeg) ![2026-05-22 12.46.50](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/3/3b19d5e68a7f130c93411bc814e15215d7f66c31.jpeg) ![2026-05-22 12.46.29](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/b/bc32a55df4d82ed08655b9ca5c8efc57cbbb00b4.jpeg) ![2026-05-22 12.46.21](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/4/4d5ab06c39e51bcac11054ce5dd7f0c9bfa3121e.jpeg) ![2026-05-22 11.53.21](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/a/ac106b9699d0bda3ec2b9c7a6c69c952c7bebfc9.jpeg) ---

Wait after looking at these pics, did I bolt the linear rail in the wrong slot? ![2026-05-22 12.46.21-1](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/0/09054b11839f76fbffc79f495480870cfd494b6c.jpeg) ---

Looks like it should be mounted on lower part of 8020 ![image](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/6/6959b0025989b8a71669c114ff72b4c53d85446c.png) ---

I went to my account and it listed 12 inch gantry, I thought it was a 12 inch . ![Screenshot 2026-05-22 125727](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/e/eed5d4ebfa1c2a228f821c214aab6e9e460b2241.png) ![Screenshot 2026-05-22 125428](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/1/12e59c929ffb5f7e19c6b139c9d84cc5e9cd9964.jpeg) ---

That looks like an 8" gantry riser to me, so you’d have to be in the lower slot. I think this is where the confusion comes in: You can have have “8 inch” or “12 inch” gantry height, and an “8 inch” or “12 inch” Z travel. Those two can be interchanged. So what you likely have is an 8" gantry riser (common) and a 12" Z travel… This configuration means your gantry isn’t any higher than normal, but that your Z can lift higher and out of the way ---

Thanks yeah I’m realizing now that I put the linear rail in the top slot and I needed to put it in the bottom thanks again ---

I did the same thing. I have an 8" gantry and 12" z-axis, I confused the two and installed per the 12" gantry instructions and noticed the conflict. That’s when the “ah hah” moment hit me. ---

Eric I am confused about this part, the routing of this sensor wire goes into this channel along with 420mm hose? Are there any vids on this? ![Screenshot 2026-05-26 133949](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/7/7c83b05e6f170ef7a7b9110640d641e850ec76e8.png) ![2026-05-26 13.35.34](https://canada1.discourse-cdn.com/flex027/uploads/avidcnc/original/2X/5/5c55dd2e09d42d5f72657f1130e5032d25bc7544.jpeg) ---

You’ve got the right idea. Wire/hose goes in one channel, hose goes in the other. ---

Are the instructions available to those who haven’t ordered the ATC yet? I’m interested in ordering one this summer at the same time I want to do some other upgrades, and would be curious to look through the installation steps. ---
