using a drag knife
this is the d2 drag knife which can cut up to .25 in material,it looks
like a simple concept but its not take it from me ,there is a lot of
programming thought went into the use of it ,as you need to run a macro
in excel to make some changes to your toolpath in order for the knife to
have its proper orientation

Re: using a drag knife
Hi to all, I have a similar problem with using the drag knife gadget in Aspire 4. I'm having some unusual behaviour when cutting a radius and am using Mach3 as a controller, an oscillating knife and exporting with "Mach3 ATC mm" post processor. The reason for using the drag knife gadget is to avoid the blade turning at sharp corners without retracting it to a safe height, thus ruining the work. Now with the drag knife the problem has be solved but when it comes to cut radii the Z axis starts going up and down as if the radius is done by segmented lines, thus taking ages to finish. I have tried different settings in the gadget and also different approaches but to no avail. Is there anyone here who’s had this problem before?
Thanks

Re: using a drag knife
I made 3 incarnations of these drag knives and came to the conclusion that for Vinyl and the likes that the small 45 deg Roland style blades yielded the best results for me in a small bearing holder .My friend used it in Aspire with good results.
