- How to set up Homing in Mach4 with the SmoothStepper, and then modify lua to add an offset to the motors after homing.
The feedrate F30 will be 30 inches per minute if your system is set to inches (or you ran GCode that commanded inch mode and never set it back to mm).
The feedrate F30 will be 30 mm per minute if your system is set to mm (or you ran GCode that commanded mm mode and never set it back to inches).
F30 in inches per minute will be 25.4 times faster than F30 in mm per minute mode.
Just before that move (or in the beginning of that move command) you can issue a G20 or G21 to force the desired units.
Program G20 to use inches for length units. Program G21 to use millimeters. - วิทยาศาสตร์และเทคโนโลยี
I've been using a ESS for over a year now and it hasn't missed a beat. They are mostly simple to set up and these videos are really helpful. Thank you.
That is great to hear and thank you for your kind words!
What for are then the Backoff Velocity fields in the ESS smooth setup configuration when you performe G1 code with Feed Rate of 30 units/min? Shouldn't it be that the machine should back off with 5 unit/min after it reaches the Home switches and then, when the switch turns-off, stop the motor (or preferably to move another xx units to get out of sensors hysteresis?
Hi, homing is not performed with any GCode commands (like G1) . Mach tells us which motors to home, and then we look at the Approach Velocity set for those motors in the ESS Config, Homing tab. After the commanded motor has stopped on the switch, we will then back off of the switch at the commanded speed in the Backoff Velocity field. We stop the back off motion once the switch turns off. If you want a slightly longer distance to clear the hysteresis zone, you can add 100 us of noise filtering to that input, and it will take that extra bit of time before it stops. If you want it to offset a specific distance , like 0.5" you can command that distance with the offset shown in this video.
I use my ess with my plasma, and mach 4....whats goimg on with THC????
We are in the final stages of testing Mach4 and THC on the ESS. We will be releasing as soon as we are satisfied that the final issues have been addressed in THC. Please follow us in our Forums here: warp9td.com/index.php/kunena/7-general-discussion/7902-mach-4-thc-plugin?limitstart=0
When will threading be added, have been using the ESS for a while and it's awesome but i had no idea when i invested in this that it wasn't capable of threading but i believe it is on the cards.
Our forum is a much better place for these questions, since there is an active thread on this topic there. Threading has been working for years with the ESS in Mach3. It is the active development priority for Mach4 now. warp9td.com then click on Forum
Awesome thanks, yes it is Mach 4 that i have, looking forward to it coming out.
Slave axis? Displacement of x and xx by different lengths?
You can home the slave axis at the same time as the master axis, and it will happen automatically. However, there is no way to tell the slave axis to move a different distance than the master axis.
Thank you. Bad...
