General Mach Discussion / Re: mach3 turn postprocessor for fusion360? (turning,threading g76)

« on: February 04, 2022, 01:13:04 AM »

good morning, i thank you.

another question.
if there a programm available which works direct with mach3?

I think the biggest problem is g2 g3 and css and threading or?

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

after some testing i got the reason.

the magnet is glued to a brass disc.
this brass disc is in a distance of 3mm to the shaft of the turret.
and now?

i looked to the bill of the magnets i bought.
this magnets are samarium cobalt sm2co17 magnets with and they are axial!
size 3mm diameter 1mm long.
holding power 250gramms.

250gramms?! i checked this with a spring balance.
ok...  the 250gramms are right.
then i loose the glue... turn arround the magnet.. the magnet holds without glue..ook..

after 3 hours waiting i take off the magnet and the brass disc.
then i start homing my a-axis... without the magnet.
whats happend? it homes correct.. without magnet.

this tell me:
the magnets are so strong that the magnet load some magnetism to the spindle and let the homing failed.

i cross test it again... i take a mini torch and heat the area on the spindle.
then i start again homing...and? no homing..

result:
the magnet loads some magnetfield and the ref/home position got a offset.
magnet must be low power or.... a lightbarrier..or a proxi switch.

1 week take this to find the failure...


thanks to all

good morning
yes all works correct.

1A 5V.

i think i will today change today to a lightbarrier. the magnet is glued to a brass disc. the brass disc is screwed to the shaft of the turret.

or must i config something on the ess?

thanks

yes all are groundee together.

my idea:

i power the hall ic via parallelport when use parallelport.

but with the ess i power the hall ic with a 5v source which is the same as for the ess.

i dont know but i think the magnetfield/range changes.
its a idea.. but i am not sure.

nobody a idea??

my solution is to use a optical sensor like light barrier with a disc and a slot.
this weekend i would check.

but i think the problem is not the sensor .. is it a setting in mach3 or in the ess plugin??


thanks

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..

Hi i own a old VFD wich works via rs485

the Protocol is the USS Protocol from siemens.

is it possible to use the vfd with mach3 via rs485?
its not modbus!

thanks

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
