Re: [Emc-users] Very neat idea of controlling the Z-level

Thanks for the link. Much appreciated. I have a machine that was formally a CNC router. The gantry ways are pretty parallel with the table surface to begin with. The real problem comes in the pcb mouning to the table. You need to make sure that the PCB does not bow upwards. I try to pre-flex

Re: [Emc-users] Very neat idea of controlling the Z-level

I am not good with programming, but I work with surfaces in mining applications all the time. Why not create an XY grid of the z surface and then load that into EMC much like one loads in a map for backlash. The grid can be created with as few as three points or as many as the operator desires.

[Emc-users] rtapi kernel must be loaded?

i go to the terminal to load rtapi as docs say cd emc2 halrun, then it gives error consistig of rtapi kernel not loaded. i would include the file but ive not yet figured out how to save it to send it to the paste bin this install disk was burned dec 16 thanx jeremy --

actually it probably can go into a kinematics module, like below I think it could work out as follows: - take grid of Z probes - compute surface parameters and pass to kinematics module via HAL pins - mill unmodified G-code The advantage would be - beyond 'no gcode translation needed' that it wou

Re: [Emc-users] Very neat idea of controlling the Z-level

just a vague idea - it would occur to me that transforming the probe result into a parametric model for the Z surface, feed that to the trajectory planner and make the TP 'do the right thing' as a move is executed would greatly simplify the usage of this method, and get rid of the G-code transfo

well it turns out if you do it exactly as the install exactly as the docs say it will work. just fyi anyone downloading emc to usb should get the infra recorder and use it to burn the image as windows defaualt burner will not work nor will nero9 as it will not burn an image from usb, well i only
