-- Hi everyone , I need some help with the home_sense and the pins associated for micro switches. The page says that the correct pins are GPIO 18 and GPIO21 (CNC Shield V3) but the last one doesnt

Is the wxtimer working as in the older versions of mach4 i still see the wxpanel and wxtimer event in the screenload script, but if i create a button and do a timer:Start(10) i get a message box

Is there a way to check if any axis is in motion, after you excited a mc.mcCntlGcodeExecute command in a coroutine so the motion is finished before another? mc.mcCntlGcodeExecute is excited ? or

Atan[3]/[20] works in Mach3 Gcode, not in an external card. If you have Mach3 on a PC with no connection to a controller or machine then you can use: G90 #50=Atan[3]/[20] g0 A#50 and the DRO for the

hello Martin I thank you very much for the time you take to help me I managed to turn the drawing on the screen with the following commands Code “G68 A0 B0 R” & Final result Sleep(150) doOEMButton

Glad I could help with the angle calculation. Here is something to consider. If you are not currently using the A axis you can make use of it. The A axis is rotation about the linear X axis and uses

hello Martin I implemented the function calls the Taylor series it worked well now, I don't think the measurements for angles less/greater than 20° are justified for me the maximum could be less

It never occurred to me that they did not implement Atan in Mach3 scripts since it is a standard VB function. There is a simple work around though using what are known as the Taylor Series for trig

Hi after several attempts Atan is not taken into account in the GCode, it is possible that the function is not implemented in the controller card (Chinese) I fell back on this formula AB = 100'

thank you Martin for this reflection, I will test all this by replacing the Z with the Y I will keep you informed of my tests it all depends on how the piece is fixed on the table

Thank you for the link but the goal is to obtain the result of the angle using a mach3 macro

Much simpler is go to this Website and enter the dimensions you have and get the result immediately. https://www.engineersedge.com/calculators/triangle_solution_3.htm Emgee

I have been thinking a little bit more on this. It occurred to me that you may be better just reading the Z axis DRO into two variables and using the difference between those two values to calculate

I just like to declare variables to remind me what is in a macro. I also like to put a really unlikely value in something that is going to be calculated so I can tell when it has been changed in the

thank you martin for this approach yes, I use a probe and GetOEMDRO(802) is indeed the Z you start by probing the Z and then do the final calculation Angle = ATAN(Zdro/20) you declare a variable:

Pythagoras will give you the distance between the start point and the end point. So if D is the distance between the start and end points up 3mm and across 20mm then D?=3?+20?? ? D?=9+400=409?

Sorry about the mix up, I thought you were chasing a length.

hi simply because I'm terrible at math c squared = my angle??

Because he’s trying to calculate an angle, not the length of a side. Sent: Monday, February 5, 2024 3:26 PM To: [email protected] Subject: Re: [MachCNC] angle calculation g68 If you are
