Homing and limit in one switch.

added ini:
HOME_IGNORE_LIMITS = True

added hal:
net Y_HOME remora.input.09 => joint.1.home-sw-in joint.1.neg-lim-sw-in
Work!


I still need to figure out why the home search has to be done so slowly.

When I hook a multimeter up to the vfd 10v in, the voltage physically drops near to Zero if a lot of speed adjustments are done. So I can see now what is happening but iv no idea why the voltage drops so much. It must be something to do with how remora outputs the signal ? 

Thats what we needed to see, but this is somewhat expected by the reading from the halscope of SP.0 . alright, well this can be 2 fold. either the RT1052 firmware is doing it, or the analog circuit is messing up. It doesnt show up on mine because Im using STM32 firmware, and Im using PWM.

Homing and limit in one switch.

Category: General LinuxCNC Questions

I am try homing and limits.For test i have only Y stepper driver installed.
Homing work.
but i limit stop not work. I need for safety and bad moves.

hal:
#Homing and limits
net Y_HOME remora.input.09 => joint.1.home-sw-in

ini:
[AXIS_Y]
#MAX_VELOCITY = 100.0
MAX_VELOCITY = 30.0
MAX_ACCELERATION = 30.0
MIN_LIMIT = 0
MAX_LIMIT = 30000.0

[JOINT_1]
TYPE = LINEAR
HOME = 0.0
MIN_LIMIT = 0
MAX_LIMIT = 30000.0
#MAX_VELOCITY = 100.0
MAX_VELOCITY = 30.0
MAX_ACCELERATION = 30.0
STEPGEN_MAXACCEL = 30.0
SCALE = 160.0
FERROR = 1.0
MIN_FERROR = 0.5
#HOME_SEARCH_VEL = -10.0
#HOME_LATCH_VEL = -3.0
#HOME_FINAL_VEL = 20
#HOME_IGNORE_LIMITS = YES
#HOME_USE_INDEX = NO
#HOME_OFFSET = -20.0
#HOME = -10.0
#HOME_SEQUENCE = 2
#HOME_OFFSET = 0.0
#HOME_SEARCH_VEL = 50
#HOME_LATCH_VEL = 50
#HOME_SEQUENCE = 50

HOME = 1
HOME_OFFSET = -3
HOME_SEARCH_VEL = -10
HOME_LATCH_VEL = 30
HOME_SEQUENCE = -1
#HOME_USE_INDEX = False
#HOME_IGNORE_LIMITS = True

I read:

forum.linuxcnc.org/plasmac/46160-homing-...ctive-before-backoff
linuxcnc.org/docs/devel/html/config/ini-homing.html

what do i need to do to make the limits work?
Why doesn't homing lock the stepper instantly and needs a monstrously slow motion for the initial search?

sorry spyder, i had a provision set up so you could do everything from ini file. just sawp these 2 lines, uncomment the one
#setp scale-rpm.gain 0.02 # 100/ rpm (5000) = .02
setp scale-rpm.gain [SPINDLE_0]RPM_GAIN # 100/ rpm (5000) = .02

for the outputs, yeah you need to change them to whatever your outputs are

Which kernel version is best for real time?

Category: General LinuxCNC Questions

Did ya set the governor to performance?

Try to remove unnecessary hardware.

blacklist kernel modules of unneeded devices.

Mask and disable unneeded services.

Ensure you have plenty of RAM; disk I/O should be avoided as much as possible.

Caching and buffering will reduce disk I/O and latency, but requires ample free RAM.

need more of 8Gb ?  i need desolder realtek from my motherboard?

Which kernel version is best for real time?

Category: General LinuxCNC Questions

Yes PCW, is the same Realtek with dkms driver for fix latency.
Maybe I'm asking the wrong question: is it really necessary to do the test with YouTube?

When you get an error, what does:

halcmd show param *.tmax

(typed in a terminal)

show?



 

 
next youtube video start i take junction error.

Actually, no. Spindle 'ON' shows 0v between COM and AI1.

Moving from Axis to QtDragon?

Category: Qtvcp

Had a bit of a break and thought a minute and I think I figured this out. There is an entry [FILTER] in the .ini file and I added a line below that PROGRAM_EXTENSION = .nc,.ngc,.gcode G-Code and not only did that work, placing it first in the list makes it the default. Very nice. Thanks for that bit of info. Much appreciated.

For the Z-180 after homing:

My startup procedure is: Starting the configuration and homing. After that the Z Axis is at -180. See screenshot attached.

For the different tool change position:

Toolchange from no tool to lathe tool:

X-Axis-Position: 250mm
X-Joint-Position: 623.2051mm

Toolchange No. 2 from lathe tool to endmill:

X-Axis-Position: 330mm
X-Joint-Position: 873.2051mm

The Y-Joint-Position is the same.

Spindle orient:
"Because this value changes instantly it would likely cause a following error in the b-axis drive " that was the missing bit of information.
