So you tried stuff AI has, what have you tried and what were the exact results ? To save repeating stuff.

Just to check if i messed op the ui file, i made a new project, just with essential items to start. The behaviour is the same. When a running a program or mdi move, and press a button with feed_percent_, rapid_percent_ ,spindle_percent_ the display stops updating for about 5 seconds. When watching distance to go in hal, this keeps moving.

 

Hey Mark,

really nice work with your Maho retrofit. I'll certainly use your gearbox component in my conversion as well

I am actually using the original M23 connectors. The assembly concept is also shown on the Github page.

These are pictures of the very first test PCB, not the latest v0.9.5
 
 

Wow, nice work.
One aspect of the Heidenhain hardware which is outstanding is the quality of their cables (double shielded) and connectors (M23). Why downgrade to D-Sub rather than making your board compatible with M23, so you can plug the scales straight in?

Hello gentelmen,

How to reduce the read-all timig from 0,8ms to something below please? Ping I have beloe 0,3ms and latency at servothread below 800ns 

I am using 7i76e+7i77 at P1 with 3 axis setup..

I have tried everything what AI told me but without any success ... 

thanks

Thank you for your suggestions. I'll test them within the next two weeks and keep you updated – I'm currently in the middle of my exam period, so my rime for the retrofit is limited :/

Hey folks, 

i'm currently retrofitting my Maho MH400E and also needed a interpolator for my linear scales. I wanted to ditch the big clunky 3 channel board of Heidenhain and also avoid the EXEs with the same reason. Without knowing about your project i started my own interpolator also based on the iC-NV and reached out to the manufacturer iC-Haus. They kindly provided some more details and also the hint to have a look at the datasheet of the iC-NQC. In that datasheet, there is a analog frontend suggestion, that can be feed with 11µA, 1V and TTL signals (the NQC is a BiSS interpolator/converter). So i pretty much copied that input circuit (ditched the TTL input) and added some lowpass capacitors like they suggested in a other part of the datasheet. In case they don't work it's easy enough to just not populate them. 

The current list of features are: 
- DB15 plug matches pinout of Beckhoffs EP5101-0011
- In case somebody doesn't use it with a EP5101 it also supports reverse voltage protection
- All inputs and outputs are ESD safe
- Current limiter for sensor supply (currently set to 120 mA - can be bridged if not needed)
- Differential and single ended output possible (manually selectable via solder jumpers or by 0 ohm resistors)
- All signal lines are length matched to all other encoder channels
- Sensor can be plugged in via pin header or RJ45 (different pinout than yours - pin matched with Heidenhain)
- Board is meant as eval board as well as "finished product". Every input can be changed via a switch or the provided potentiometer

At the moment i'm at version 0.9.2, that's the first "finished" pcb layout, the texts for the switches, testpoints, ... are missing. I'll get to these in around 2 weeks, when my exams are over. 
You can find the project here on Github: github.com/PedPEx/SinCosEnc-Conv_EP5101
When you have any inputs on that project, just let me know   

linuxcnc.org/docs/2.6/html/gcode/gcode.h...ec:G83-Drilling-Peck
Doesn't seem to be supported. I also checked the code, interp_cycles.cc (always learn something new)
but no IJK.

thanks, but still a lot of work to do (At the moment it is still a proof of concept):

 

here is the latest source file:

# python3 testme-graph.py riocore/configs/Tangbob/config.json
 

Thats really neat is it part of the dev branch?

guten morgen,
danke für deinen denkanstoss
die kombi glaub ich wird es werden 
7i95T + 7i83 + 7i73

Dann bringe ich das Vorschub Potentiometer auch noch unter auf der 7i73
in summe wären das dann 
Step/Dir Ausgänge    6 (differenziell oder single-ended)                        7I95T
Encoder Eingänge    6 (A/B/Z, TTL oder differenziell, ~3 MHz)             7I95T
Digitale Eingänge    24 isolierte Inputs (4–36 V DC)                              7I95T
Digitale Ausgänge    6 isolierte Open-Drain-Ausgänge (bis 36 V/2 A)    7I95T
Analoge Ausgänge (±10 V)    6 DAC-Kanäle, 13 Bit Auflösung                7I83
Digitale Eingänge (GPIO)    16 (für Taster/Schalter oder Matrix-Keys)    7I73
Analoge Eingänge (0–5 V)    4 (für Potentiometer etc.)                            7I73
Drehgeber / Handrad    1 Inkremental-Encoder-Eingang (MPG)               7I73

und angeschlossen an die 7i95T über die beiden Serial mit RJ45 Open end kabeln
 
wo wir aber schon beim nächsten problempunkt wären.
Wie weiß PNC conf das wir an der 95T auf eine 73 und 83 angeschlossen haben 
eine spezielle firmware auf mesa habe ich nicht gefunden. Das sind viele fragen 

Danke und alles gute
 

Probably in the next month second half.

in the io-samurai project you find example, in the main.c line #88 (detection & init) and line #172 is the draw process, i not used in the stepper-ninja project because its limiting the refresh speed of the inputs/outputs (~60/sec), but if you are want to use to inputs and outputs for control panel, its probably not a problem. If you want to participate the project please use the test branch.

 

Hello Everyone,

I was searching thru forum and internet for possibility of G83 deep drilling canned cycle with variable peck depth using IJK word in LinuxCNC, I didn't find any example or reference for that. 


Is it possible to achieve this thru macro ? I want to drill deeper 20xD several 100s holes in circular bolt pattern. Any guidance? 

Hole is exiting at an angle so any idea how to program slowing down spindle at every depth . 


Thanks in advance.
