It's still a work in progress, but the computer is now mounted on the tray where the original controller used to be. It's quite convenient since the tray folds out of the cable cabinet, making the computer easily accessible.
 

Good on you. Nice work getting another Maho going.

Thank you, Mark. Your MAHO videos are actually the reason we decided to get a MAHO and go ahead with the retrofit.

Aciera,
Thanks to your help, my project is almost finished now. I couldn't have done it without you. First of all, I would like to thank you very much. I am currently planning to put the limits and axis calibrations in the gui, but I do not know where the settings page is, I can change the home page, but I cannot access pages other than the home page.

The documentation located here indicates the following:

To have the manual spindle buttons also incrementally increase/decrease speed:
#action_spindle_fwd{
qproperty-spindle_up_action: true;
}
#action_spindle_rev{
qproperty-spindle_down_action: true;
}

Is this correct?
I've not been able to find a file where this (#action_spindle_fwd) is located?
If it doesn't exist is there a specific file or block that I should add it to in order to get this functionality working?

I did find this entity in the qtdragon_hd.ui file:
<item>
<widget class="ActionButton" name="action_spindle_fwd">
.....
</item>

Is this where it should be added?
 

I have the same problem. I've noticed that Linux itself has actually lost connection with the device, which I can see by running $lsusb while the pendant is working and again when it's not. The odd thing is that restarting LinuxCNC seems to mount the usb device in Linux.

I don't know the solution, but I'll continue taking notes and report back if I figure it out.

Those seem to be unused so irrelevant
 

ANALOG_SCALE_MAX = 133
ANALOG_MIN_LIMIT = -133
ANALOG_MAX_LIMIT = 133

Is correct ?

SCALE =  133 
(or possibly -133) to get the feedback direction correct

MIN_LIMIT = 0
MAX_LIMIT = 1000
MAX_VELOCITY = 120
MAX_ACCELERATION = 300

SCALE = possible 133 but Not sure what this is without seeing its use in the hal file
ANALOG_SCALE_MAX = 133
ANALOG_MIN_LIMIT = -133
ANALOG_MAX_LIMIT = 133
ENCODER_SCALE = 1000      (2500*4)/10

HOME_OFFSET = 0
HOME_SEARCH_VEL = 5
HOME_LATCH_VEL = 0.5
HOME_FINAL_VEL = 20

My setup is as follows:

Motor 1600 rpm  - 10V anlog
pulley ratio: 14/28 = 0.5
leadscreaw pitch = 10 mm/turn
Encoder : 2500 PPR

 

So,

My INI file should be

MIN_LIMIT = 0
MAX_LIMIT = 1000
MAX_VELOCITY = 133.3 (1600 tr/min * 0.5 (14/28) *10) =) 8000 mm/min =) 133.3 mm/s
MAX_ACCELERATION = 300

[JOINT_1]
CARD = 0
TAB = 1
AXIS = Z
MIN_LIMIT = 0
MAX_LIMIT = 1000
MAX_VELOCITY = 133.333
MAX_ACCELERATION = 300
TYPE = LINEAR
SCALE = ????????????????????
ANALOG_SCALE_MAX = 10
ANALOG_MIN_LIMIT = -10
ANALOG_MAX_LIMIT = 10
ENCODER_SCALE = 1000      (2500*4)/10
FERROR =  0.005
MIN_FERROR =  0.0025
DEADBAND = 0
P = 1

WHAT should i put SCALE Value AND MAX OUTPUT ?

I cant help you with your comp, but good on you for retrofitting that cool lathe.

Photos or it didn't happen

You guys describe these machines without showing us. That is torture.

Good on you. Nice work getting another Maho going.

Hello, I would like to thank you for the E-Stop routine HAL. It saved me good couple of hours of head scratching:) Your build looks amazing! M.

So I tried to adjust my drivers,

I started to set zero offset, I didn't feed the analog and I set the motor to slip as little as possible.

I powered the analog at 10V, set reference input at 10V and set tacho input at 1600 rpm. so 10V-1600 rpm.

as for the de I and epsilon settings, I have leave as it was either set to full.

as for speed stability, nothing happened when I moved it, except when I started to set it to full, a buzz appeared but nothing visible on the motor rotation.
