I’m just starting the Titan series on a Tormach 1100MX. I’m fairly new to CNC. Dont really understand how compensation type works very well on the Tormach. Using Fusion 360 CAD and CAM, Tormach Tutorial: Program the 1M.
This is the error I get on the finishing path of the outside of the part using 2D Contour. Same exact settings as in the video. Left climb, wear for compensation type.
“Length of cutter compensation entry move is not greater than the tool radius”
“Line 23: G1 G41 X4.0298 Y-2.104 D3”
D3 is the .375 flat end mill tool being used
G41 Cutter comp to the left of the programmed tool path
@JerryChapman its been a while since I did the 1M. Check to make sure your lead in & out is set as the video. My understanding of CC is the lead in and out must be at least 1/2 the tool diameter. Im not sure how Fusion can comp a .375 tool in a move of only. 01
That being said try changing the lener lead in & out to .1
Maybe I’ll tag @Billy-Boyce for now to hear his view point
I constantly have compensation errors with pathpilot. I get around them by setting the the tool diameter in tool offsets (in pathpilot) to a low number like 0.01.
Maybe its a crappy work around but it gets the job done. I dont know if its a problem with pathpilot, the post processor or what. But any code I produce from camworks or fusion seem to end up with these issues. As well as stupid G41 repeat code.
Set your tool diameter in Path Pilot to 0. Should your feature be undersized then you would set the tool diameter to a negative value (depending on value undersized will determine what to set your tool diameter). In my case i had a pocket .125 in diameter was a bit undersized and i slowly walked it up using cutter comp. I needed some locating pins for a fixture I was working on and used this method to make sure I didn’t make this hole oversized. I think I started out with 0.0001 and worked my way up until I had a perfect fit.
Keep in mind for my .125 hole setting my diameter to -0.0001 * 2 for the other side of the hole (just like a lathe).
