Hey guys me again, before I start .ini file is include and two pics of the machine so you can see position of the switch understand me (pic of cat is how I feel right now)

So as the title says my Home switch is set up on the right side of my table, and I'm trying to set up 0 to be the centre of my table. I have edited my .INI file so that min is  -111.5 and max is 111.5 (As my max travel is 223 so that should put zero smack bang in the centre... I hope?)

Problem is the machine keeps looking for the homing sensor on the wrong side of the table as in it travels in the wrong direction. I've read a few other posts and someone said that a - or + in front of the HOME_LATCH VEL will change the direction it looks for the home in? But changing that seems to not do anything.

The only way I got this to work was flipping all axis in the gui editor then it works flawlessly but... then all my parts are mirrored which I don't want.

Thanks again guys, as always hopefully Im missing something super easy -_- 

 

If using HALUI, then you have up to 64 commands, but IFAICT one command per INI line.
if using Qtvcp/Qtdragon there are more options.

Spent some time reading up how to flash this thing and... it works! Thank you very much! Problem solved.

Also, I'm surprised I've been running it this whole time with no issues. 

Nicely done, maestro, thank you.

Very nice build, thank you.
Reminds me, i have a mac pro with cnc controls in it somewhere in the shop, pretty sure it is under the main table (out of 11 tables).
Are those 4590 made by Bosch/rexroth ? I had plenty of those, now i have some very short parts! The best thing is they work with M8 nuts/bolts perfectly and the aluminium is very high quality as you can tighten and loosen those bolts hundred of times without issues, in the same place!

Pardon my ignorance... Based on your comment I presume that the servo tuning is stored in the servo drives?

I have had the understanding that I DO want the LinuxCNC feedback loop in order to make a [more] closed loop system which is more better than having the control completely blind to the position (or loss of position) of the motors.

Seen this after i already replied above.
Yes, in position mode the loop is closed in the drives, so the tuning is done on the drives.
Since LinuxCNC can do steppers with feedback and loop closed in LinuxCNC, it is much better to use the drives as is as they are already tuned there, and tuning steppers with feedback is much, much easier than analog servos.
Another good thing is there is no fear of motors running at full speed if any mistake is made during wiring and tuning in analog mode as the drives have no control over motor speed in that mode, they do whatever is required from the analog input.

7i96S + 7i85 or 7i85S and add a 7i84 if you need more IO.
Later, when you do feel confident to dip your toes in analog territory you only need to get a 7i83.

You would need to use 7i92t_5abobx2d.bin firmware to match that BOB
 

I'll get these motors and drivers any day now. I'm gradually figuring out the configuration. And I have a question, why specify these empty blocks? Will it work without them?

 

EDIT: Yes, they are needed.

@Grotius

the model/gcode is in inches for that last video..lol  maybe try it in inch to see the correct moves? 

i couldn't tell if the machine was moving..lol
 

Exactly, i did implement it, i dont know why the video is not embbeded. This is my second attempt

Attached the kinematics file, you will find two kinematics ,it works out with kinematics switch.
Basically is a custom lathe i built that is has X, X', Z axis with motorized tool where X and X' works together to form a Y axis, this would be kinematics 0.
Kinematics 1 is this cilindical mapping, where it must work in combination of:
  -First reference de spindle
  -C axis is always present but not used until kinematics 1 is activated (but spindle encoder is always linked to joint.xx.motor-pos-feedback pins in hal
  -Remapped Gcode G7.1:
      G7.1 Rxxxx for activating the transformation on specified diameter
      G7.1 without R to deactivating the transformation


Any questions are welcome

 

This is my high power (3W) LED soldering machine. It holds the LED in place, displaces solder and heat the connection with a regular soldering iron.

It uses mostly ngcgui to handle the logic. It has some basic features like resoldering failed joints and a couple more.



It also displaces thermal greese with a interchangeble module. This video also shows how led's are placed in bulk.



It's unfortunate I can't open the source for this project because I did it for a company. But, anyway, it is quite simple to replicate. Nothing fancy. I hope it helps someone.

Hi everyone, I've managed so far after all these years to get all the info I need on these boards by being a lurker, so thank you everyone for all the knowledge on here. I'm at a crossroads with this one though as I'm still quite new with the mesa boards.

I have the following BoB below and can confirm I can get the PWM working using software stepping by setting it on Pin 1 in the Stepconf wizard.




When setting this up using the Mesa board (7i92TF), I followed the guide below which works perfectly fine for running my steppers.
forum.linuxcnc.org/49-basic-configuratio...rallel-port-bob-g540

What needs to be changed on my setup to get this working? Mind you the config on my mesa board is whatever came straight out of the box.

My intention is to use this PWM signal to control a laser since I mainly control my spindle manually (or RS485). I'm currently testing this potential laser setup right now with an LED. If this helps, one thing I also noticed differently between software stepping and the mesa board, is that during PC boot the LED is already lit versus when it is connected to parallel port it is not.

I've attached my INI and HAL file for the mesa config. Any help would be appreciated, thanks!
