Using G64 with M66 for smooth robot control

Category: General LinuxCNC Questions

Have you thought about using the python interface to issue MDI commands to the queue instead of running a parametric gcode program?

The positional values are determined by a camera running object detection.

We're using it for a pick and place system so sometimes the entire move is known ahead of time (when object is being placed) but sometimes i want to change the target depending on camera feedback.

Has Anyone used DeskProto

Category: CAD CAM

Hello, I have been using Deskproto on Linux for years now, with a 4 axes CNC6040 (in fact the 4th axe is a rotation axe). It works great, it is stable. The support is good. The price seems OK for the value (hobbyist version). My setup is Blender + Deskproto. For carving, I use Aspire. I have not checked the latest version of Deskproto, which does carving. I have done a number of projects with very satisfatory results, on wood but also brass and titanium.

thanks it worked for me,
only one thing: first i found where is the location of libethercat.so files for me.
i mean these three files: libethercat.so.1, libethercat.so.1.1.0, libethercat.so

then i copied them to the /lib/x86_64-linux-gnu/

then by running your edited make file the problem solve.

Please don't create multiple threads about the same topic as it will invariably create confusion. I have deleted your other thread.

Where are you reading those positional values from and how far in advance are they known?

Good morning, to no home index, try this code in the INI file, but be careful, there may be severe collisions if you exceed the machine limits.

Using G64 with M66 for smooth robot control

Category: General LinuxCNC Questions

Hi, I've been using linuxcnc to control my delta robot arm through HAL pins and M66 commands.
This is my GCODE
(AXIS,stop)

O500 WHILE [1]

( Main loop )
M66 E0 L0 ; Read from motion.analog-in-0 (X)
#1 = #5399 ; Store the read value in variable #1
M66 E1 L0 ; Read from motion.analog-in-1 (Y)
#2 = #5399 ; Store the read value in variable #2
M66 E2 L0 ; Read from motion.analog-in-2 (Z)
#3 = #5399 ; Store the read value in variable #3

G1 X#1 Y#2 Z#3 F1000 ; Move to the new position


; G4 P0.1 ; Wait a short time before the next read (optional)

O500 ENDWHILE
M30

I connect custom pins to the motion analog in pins and then set the xyz values in my python or c program.
This works great, but when I try to add G64 blending to make the robot keep its speed it doesn't work.
Obviously this is because the trajectory planner doesn't know the next target point until it's read by M66 in the next gcode loop, so I tried adding the next target point into the gcode as well with 6 analog inputs:
(AXIS,stop)
G64 P50
O500 WHILE [1]

; G4 P0.001 ; Wait a short time before the next read (optional)

( Main loop )
M66 E0 L0 ; Read from motion.analog-in-0 (X)
#1 = #5399 ; Store the read value in variable #1
M66 E1 L0 ; Read from motion.analog-in-1 (Y)
#2 = #5399 ; Store the read value in variable #2
M66 E2 L0 ; Read from motion.analog-in-2 (Z)
#3 = #5399 ; Store the read value in variable #3

M66 E3 L0 ; Read from motion.analog-in-3 (X)
#4 = #5399 ; Store the read value in variable #4
M66 E4 L0 ; Read from motion.analog-in-4 (Y)
#5 = #5399 ; Store the read value in variable #5
M66 E5 L0 ; Read from motion.analog-in-5 (Z)
#6 = #5399 ; Store the read value in variable #6

G1 X#1 Y#2 Z#3 F30000 ; Move to the new position

G1 X#4 Y#5 Z#6 F30000 ; Load next position


O500 ENDWHILE
M30

This only works for every other point, because when the gcode loops, the trajectory planner has no information about the next point.

What I would need is to load the next target point into the trajectory planner so that G64 can use it, but not go there with G1. I tried adding O500 continue between the G1s but then the gcode is smart and ignores the second G1.

Is there a way to do this?

Good morning, my friend. Unfortunately, there won't be a ready-made cake recipe. Each machine requires a different methodology. I would start by studying the electrical part of the machine, to find out how many inputs and outputs it has, then how many movements it has, and finally which devices will be used. With this, you can get an idea of ​​which electronic boards from the manufacturer Mesa  store.mesanet.com/ will be necessary for the Retrofit. If you post the electrical part on this forum, we can help you.

Can the stepgen LPT work in conjunction with the mesa card?

Category: General LinuxCNC Questions

It is a PCIe Mesa 6i25 with 7i76 plug and go kit. I do not know when I updated Linux CNC last time on that device. Must be a two or three year old installation.

I do not think it will make a difference, besides the naming conventions in the hal files.

How I did it:
a) create a Machine configuration with stepconf
b) create similar Machine configuration with pncconf

Then I deleted the axis information from the pnconf generated file, for the motors that will run on the parallel port. I deleted all the axis information from the stepconf gnerated file, that will belong to the Mesa card.

Then I merged the two configs step by step by copying the "Mesa stuff" into the LPT configuration. (ended up with a convoluted hal and ini file that works and contains snippets of "both worlds")

Greetings Timo

p.s. I did not have mentionable prior experience, so it took a while to get it "free of startup errors", but no involved adjustments. Mainly removing double entries and correcting my own typos.

Turned out to be not too difficult, adds an entry 'show_startup_message' in the .pref file:
