Did you even try changing the Q to an A? Change the Q to a 0. You will be forming the thread as opposed to incrementally cutting with the leading edge of tool. At no point in the machining Industry has any machine been delivered from the manufacturer with guaranteed training on its use. The machines do not come with brains. You are expected to actually use yours.
I donāt agree with that at all. This is a cheap entry-level machine that uses some non-standard programming. I donāt think itās too much to ask for some factory support.
How is that working for you so far? It is designed from the factory to turn standard 60 degree threads. It does an outstanding job of that. If you want it to do non standard threads then it is up to you to learn a little about G code to have it do what you want. I was going to mention a G32. It is a single pass cycle at a set feed rate. Mainly used for formed threads. It requires the user to write a G32 line for each depth of cut. You are not really capable of that. You woukd just get on the forum and blame Tormach and their tech support for not writing the code for you. Since you purchased a machine you donāt know how to use unless it is just fill in the box on a conversational page.
Gentlemen,
Keep it civil. Insults thrown back and forth are not helpful for any party and if continued will not be tolerated.
While these are the official Tormach forums we have a strong preference for this space to be community driven rather than being a method of contacting Tormach. If a question is posed that does not appear to be getting any traction from the community we will of course chime in to provide an answer, but if discussion is occurring we will usually let it continue without intervention.
Michael, please open a support ticket with the details of your issue, that is the correct avenue to ask for assistance with your machine. From your posts in the thread Iām not actually sure what the specific issue you are having is (ie, whether you are not able to get code that will run or you are just not sure of the entries for coordinates). We are certainly able to provide some direction for you.
Donald, I would caution against throwing out examples of code from other CNC controllers without providing a disclaimer that it likely will need modification. G code is somewhat standardized but the differences are largely a show stopper to getting anything functional. Eg, in our flavor of G76 I is the difference from the initial X position to thread peak and D is amount of taper. G32 is also not used in Pathpilot. Other than our own documentation, that of LinuxCNC (which Pathpilot is derived from) is most appropriate; we largely try to make additions to it when needed rather than alterations.
Thank you,
Norman
Yes, I do not know how to write that code. Thats why I am asking on a forum. I am not a machinist not am I trained in how to write code. Thats why I am asking how to make it cut acme threads on a forum. I use the the conversational page because I am not a trained machinist and I am not trained in how to write code and that is why I am asking on a forum. See the trend here? If you dont know how to set the 8L up to cut metric trapezoidal threads its OK to say āI donāt know how to set the 8L up to cut metric trapezoidal threadsā instead of berating me for not knowing how either.
I need someone who does know how to write that code to tell me step by step how to make that happen. If you dont know how and are just throwing out guesses based on what other machines do that is not helping me. Go comment on other questions. Do I need someone to hold my hand and help me through this because I have no idea what Im doing? Yes. I think Ive made that abundantly clear.
Click on edit code highlight the q30. Change it to Q0. See if that makes a difference. If you can run a tap through the threads and fix them it canāt be that far off. If the angle is way off then the thread will be extended and have a saw tooth finish. Tall formed threads cut much deeper than you think. Are you letting the cycle finish? You may just need to go the the offset page for the tool number and increase the offset for them to cut deeper. What type of threading bar are you using? Steel or carbide? The steel will deflect and chatter more than carbide.

Knocking Q down to zero did the trick. Cuts surprisingly well now
