Hm, interesting. It might be worth considering an issue that usually only pops up once the machine is finished which is: How are you going to create gcode for this?

Hello everyone, I'm very new to everything Linux related but frustrations with my current machinery has led me down a rabbit hole. Here we are.

I saw people asking for feedback on running the 2.9.2 package on a raspberry pi. I have a Raspberry Pi 4B 8G model that I have attempted to boot the 2.9.2 image to with very little success. I used the XZ file on the downloads page and put it into the Raspberry Pi imager, the board was booted with a small touchscreen plugged into it's display port via ribbon cable. ACT/power lights appeared promising until I got a peculiar message showing up on screen with some skulls. I have attached it here.  

After the skull message, power light turns off and the ACT light switches to a faint, consistent flicker while the display continues rotating through solid colors. 

It's entirely possible that since this is the second time ever using one of these that I have royally screwed up somewhere. I have also read some negative reviews as far as the compatibility of the 8G model goes so it could have something to do with that. Any and all info you guys could provide would be greatly appreciated. Thank you!

[Edit], the XZ file taken off the homepage for version 2.9.2 failed to flash using BalenaEtcher 

The solution was so easy...
In toolchange.ngc file I copied that lines

M68 E0 Q#<selected_pocket> ;set the carousel to move to the right pocket

M64 P0 ; start carousel
;G4 P2
M66 P0 L3 Q60 ; wait for carousel finished
O210 if [#5399 LT 0]
(abort, failed to align carousel)
O210 endif
M65 P0 ; stop carousel

And inserted them to after that line

O100 IF [#<tool_in_spindle> GT 0]

Now I can turn carousel to any position for changing tools. And after that making M6T. carousel back to pocket from before loaded the tool and unload them in right pocket..
But still after change the tool popup screen to confirm like in manual change...
Any help with popup screen??

 

 

Hello guys,
I'm looking for an advice to buy the right VFD for the spindle with the following specs :

P = 2 KW
L = 4.5 A
2 poles
380 three phase
Hz 267 @ 16000 rpm
HZ 667 @ 40000 rpm

here are the specs of the ms300 VFD11AMS21AFSAA i'm thinking to buy :

2.2 KW
Input 220 single phase (so I don't require 380 three phases at all)
600 hz
Output current 11A
Built in EMC filter

Here are the CMM-EC02 ethercat expansion board features

► Supports EthernetCAT protocol
► Supports standard CiA402 speed mode
► Supports SDO (Service Data Objects) function: Drive status reading and parameters editing
► Auto shutdown function for interruptions during data transmission
► Supports remote I/O function


I'm not experienced to choose a right one without asking, this model should fits? It caps at 599hs so I should reach appox 36000 rpm? (old one seems 480hz).

Here is the delta ms300 catalog  filecenter.deltaww.com/Products/download...00_C_EN_20210714.pdf

I have an old kappa-goniostat (crystallography) that should be disposed and it's breaking my heart. It has 3 rotational axis for the sample in middle of the goniometer and an additional rotation+translation axis where originally detector was mounted.
I had this crazy idea that one could use it to work on spheric shapes in the wood (think about Escher's "Angels and Devils").

Two main problems:
1) I'm newbie to linuxCNC
2) goniometer has a strange geometry. I've attached image how it works.
The object rotates in center of system with three axis omega, kappa and phi. The kappa-angle is 50° to base (or 130°).
I tried to read examples about 5-axis geometry but all of them describe systems with orthogonal axis.

Any suggestions on how I should start this project? I have no idea how to tackle kinematics.
And before I spend hours reverse engineering encoders on DC motors, I need to know whether it is actually possible with LinuxCNC.

all best, Kris
