Mach4 General Discussion / set machine axess position 5 axiss+
« on: October 20, 2022, 07:53:20 PM »
we use abs encoder
we have other application that connect by RS485 chain to all drivers and inverter ,and read the ABS position
the only way we found can change mach machine position was by set homing as " home in place"
and change the offset value by external script(API) then when run homing its update the position
this have some problems ,but min time we find solution all
but still have one big issiue
when we have large axiss (6 axiss ,but there not all work paralel ,one is lath ,one is spindle hood...)
and when we run program  but in program move only with 3 or 4 axiss
one of the other extra axiss have small movement(something like 0.5mm each start block)
this small movement  are not noise ,the movement are comad from mach can see on screen
and main problem after several working the machine stack in soft limit because that axiss
****when we change back homing to normal this problem go

i have question about the way work with modbus
i can each  time i want data or send data open the com send then close the com
second way is establish the com then not close it until close much
first option have advantage that less problems with com fail and save computer time

Mach4 General Discussion / Jerk ,S curve
« on: September 22, 2021, 06:34:54 PM »
hello every one
i use mach 4 for about 3 years more then 20 cnc
i always had acceleration problems ,but i always blame the chines structure
until we open our work shop and start produce our cnc ,but ...same problem cant get normal value for the acceleration without having vibration
 today we found the at least the reason
mach don't support S curve
i know this the reason because when we use the driver filter(its act similar as S curve)this vibration go even with high level of acceleration
after this long story i ask mach engineer ,please try put attention for this
its very very important(solve it by the driver its not correct way)please try solve this point
thanks
