Fusion 360 tool change and lack of clearance height (Fadal 88HS)
Hi all
Wonder if anyone has a good post processor for the Fadal88HS?
I've messed around with the clearance height and retract heights but after the initial tool change the second and following tools are not at a safe height when transiting across the workpiece. I feel it's a post processor issue but I'm not real familiar with modifiying them.
I usually like to have a safe Z of 2" but this will initially start the spindle well above the workpiece and turn flood on but on subsequent tool changes it seems like it drives the tool down to top of stock, starts spindle then transits at maybe .1" above....gets to say new hole location, retracts to clearance height goes down, then feeds to depth, retracts to just above workpiece height then transits across workpiece again, instead of going to clearance height.

Oh? I was using another post from a fusion 360 chat. Called CNC88HS Fadal / 1444_CNC88HS
I will try with the Fadal.cps post.
You ran it on your machine with no issues? After T17 when it goes to the T3 centerdrill it's starting up the spindle just above the material as opposed to Z0 from the tool change....same with the T5 drill cycle...then it damn near crashes across top of stock...

Your code looks pretty messed up, yes you are getting the G28 G91 Z0 before the tool change but then you appear to have a Tool Height Offset being called before the Spindle start, why that is on the same line as the Tool Change so the machine is more that likely going to the start position of the next operation.
Without seeing your Fusion f3d file I can`t see how you have your heights setup in each operation because I don`t see any in your code.
Can you put your Fusion f3d file in a Zip folder and upload it so someone can take a look at it ??
