« on: February 01, 2024, 12:43:19 AM »

Hi!

all is done but i struggle with the uc300eth.

its a 5v output which i connect direct to the uc300eth.

somewhere i read that uc300eth needs abz sensor?! can someone tell me what is wrong??

« on: June 17, 2022, 08:24:08 AM »

Hi guys...

i build a lathescreen.
now i have on 3 sites the same button with the same code...

if i want to change something on the code i must copy&past it to all 3 sites...

is there a way to to make changes in a .m1s file?

my attemp was:

button starts oem code 34 (basic script)
in the line for the script i put in :

Code "Button1.m1s"

then i make a file in the correct directory with the name Button1.m1s
to test it i put in the file :

Code "F300"


i get error when i hit the button in mach3....

if i  name the file M4444

and change on the button from button1.m1s to m4444.m1s it works.


what do i wrong?! thanks

Mach Screens / machscreen .. adding dro and script from button??

i wrote a vbscript and save them.in the macro folder.

name of the script is HomeTurret.

now i want to load this script as file when i hit the button.
if i change something on the script i dont want to add the script again with machscreen.

is this possible??? can someone help me?


2.

when i do a toolchange my turret jogs to x5 z55.
this values are named wzwx and wzwz
i add 2 dro to my screen.
i wish that the dros show me wzwx (5) and wzwz (55).
and i want.. if i change the value in the dro.. that is set wzwx and wzwz to this.

example : in the dro i put in 10 and 60.
then the machine jogs to x10 and z60.

its to set a toolchange position.

is this possible?!
thanks

General Mach Discussion / Emco Compact 5 cnc Retrofit problem (Turret,Ess,Parallelport)

« on: November 02, 2021, 02:30:14 PM »

Hi!

i get some daily trouble with my retrofit.
all works but the turret have RED DAYS
Problem:

i done my retrofit first without the turret.

for Spindle index, homing x and z i use hallic called 44e.

all works correct.

the i convert the turret to a nema17 stepper and a hallic 44e for reference/homing point.

the homeing position is on a point where the pawl is in contact and secured. its tool1.

i done all on the desk with parallelport.

it works everytime correct.

then i connect all to the ess.
and now? the homing dont work.
nothing is changed on mechanic,electric,wiring.

the homing travel less.
and get not in contact.

if i changed to parallelport... it works.
back to ess.. pawl not in contact.

i only loose my parallelport cable and put it in the socket from the pc or ess.

it takes second.

i only open mach3 with parallelport or ess. all settings are the same.


any idea? for me it sounds that i must config something on the ess.


thanks for help..

General Mach Discussion / Old VFD with USS Protocol and Rs485? need help

« on: August 01, 2021, 09:08:27 AM »

hi i have a old vfd from siemens.

it used a Protocol with the name USS.

it works over terminal via rs485 adapter.

but i want to use the vfd with mach3.
i use the vfd with pwm to 0-10V and 2 Relays.

first relay for start stop
second relay for left/right

works fine but is it possible to use the vfd via modbus or a plugin?

i attached the protocol pdf file

General Mach Discussion / Mach3 Ess SmoothStepper Threading and Index pulse

« on: June 03, 2021, 04:08:34 AM »

Hi!

i need a little bit help..

i run a standart Emco Compact 5 with Mach3.

Yesterday i machine a Disc with one hole to insert a magnet.

This disc is mounted to the Spindle.

I use a Hall Ic to get the Rpm/Spindle Position.

Its 1 pulse / rev.

then i found a encoder with only A B Channel.

what is now better?

Encoder 600 lines 1 rev
Hall ic with magnet 1 pulse rev

both together?

i set the prescale to 600 and get no threads i get crap.

with the 1 pulse all work fine.

is it a configuration problem?

thanks

General Mach Discussion / Mach3 Using 2 Axes both slow down?

« on: December 20, 2020, 06:38:20 AM »

Hi!

I am new with mach3.
I built a desktop cnc mill with grbl as controller.



Now I convert a mini lathe to cnc.
The lathe is a emco Unimat3.
Its a Toy:) and for me its a project to learn more about cnc turning.

I got one Problem!
If i drive 2 Axis in the same time both will slower if i drive only one Axis.
The Distance is correct! I dont loose steps! Only the speed goes down on both axis.

example:

I drive the Axis over the Arrow Keys on the Keyboard.

I drive Z in - and hit then + X the Z axis speed goes little bit down.
when i release +x the Z Axis speed up.


My Setup:
A Thinkpad X61 with Dock and WinXp/Win7 in Standart-Pc config

ParallelPort

Tb6600 drivers at 1/4 Steps and 1.5A/1.7A peek

Nema17 Steppers 1.7A with Gt2 belt Ratio 2:1

32V 5A Labor PPowersupply on 30V

Shielded wires between Tb6600 an Parallelport

Shielded wires between HomeSwitches and Parallelport

Shielded wires between IndexSensor and Parallelport

My Kernel Speed set to 100khz after testing with drivetest

My Motor Tuning is:
Steps/mm 1600 (microstep 1/4 ratio 2:1)

Velocity 300
Accleration 50
Step pulse 2us
Dir pulse 2 us

Step and Dir with 2us is incorrect or?
Tb6600 datasheet said minimum 2.2us.

Is this the failure? a change to 3us brings nothing.


thanks for help!

General Mach Discussion / Mach3 How to use A Axis(Stepper) as Spindle?

« on: October 15, 2020, 09:18:56 AM »

hi!

i have bought a rnr motion control eco v2 usb unit.

this unit not support dir/step on spindle.

now i want to use my A Axis as Spindle.
my A Axis is a Nema34.
i know that a stepper is not a good choice.
i want to test something and play arround.

i read that SwapAxis(3,6) change the A Axis to Spindle.
but if i enter this in the commandline in Mach3 i got an error.

how is the swapAxis function to use?
where do i enter it?

thanks
