First day trying to operate my Onefinity Journeyman. I’m just trying to surface the spoil board. I’ve created the g-code file with Carveco Maker according to a video I watched. Now I’m trying to run it but get the following message; ERROR: Z axis position 25.4mm is greater than maximum soft limits 0mm The Z gantry is in the lowest position. I am using a 1” flattening bit. What have I done wrong and how can I fix it? ---

Your Z-zero in Carvco is likely different to Z-zero you set on the 1F. ---

Have a look at this it will help you. [https://forum.onefinitycnc.com/t/help-my-toolpath-says-under-or-over-with-videos/1982](https://forum.onefinitycnc.com/t/help-my-toolpath-says-under-or-over-with-videos/1982) ---

Raise your z-gantry up or try pushing your bit 25.4mm further into the chuck, if you can. ---

Hi Craig. The shank on the bit is short enough that it will go all the way into the chuck. Is that safe? I can try raising the z-gantry up to the middle holes but I don’t know if the bit will reach the surface. FYI: As far as I can tell it’s all about the bit. I’m using Carveco Maker and selecting 2703 Surface-Planing 1" Diameter. In the Tool Path Summery I get “Tool: [1] ERROR”. But if I switch to a .25 endmill I get a more favorable message “Tool: [1] 0.250 inches dia. slot drill”. This leads me to believe that the machine doesn’t like the size of the tool/the outer limits of the tool path/size of my spoil board cutting area/or possibly something else. I tried offsetting at .25" steps inward of the outer tool path but that didn’t change anything. Also, I’ve got an Align Carbide 1” spoil board surfacing bit that I want to enter into the tools database. Align Carbide doesn’t give any of the specs on their web site that I need to create the new tool. I’ve written to them but no reply so far. That’s why I’m trying to set this project up with the 2703 Surface-Planing 1" Diameter tool that is preloaded in Carveco Maker. ---

Hi Andy – that sounds like a likely issue…unfortunately I have no idea how to find or solve that. I can re-zero the Z again and again but nothing changes. User error is my middle name, but there is usually a simple solution for it. I’ve found that if I change the bit in Carveco to a .25 endmill the error goes away in the Toolpath Summary. Obviously I don’t want to surface my spoil board with a .25” endmill bit so I’ve got to figure out how to fix the error in CM first, then try it again on the 1F. ---

Hi Yvon, Yes, lots of good info on the 1F in that link but I think the problem I’m having is with Carveco Maker and the g-code file I’m creating. When I look at the Toolpath Summary, it shows an ERROR for Tool (1) when I set the file up with a 1” surface planning bit. If I switch it to a .25” endmill bit the error goes away. Obviously I don’t want to surface my spoilboard with a .25” bit so I’m at a loss for how to solve this. Thanks for the link. I’ll read through it again to see if there’s anything I’ve missed. Cheers! ---

I remember the first time I was trying to surface my spoilboard with a 1 inch surfacing bit it wast’n able to reach the board I got that error me to , so I switch to a 3/4 inch strait bit , and all was good.
