How to change From running mm and run inches

[Lnellist69]

I just can’t Get a good answer on this subject I send everything over from a processor in inch bases mock three but it still cuts out the pieces in millimeter instead of inches how can I correctly fix this problem I’m beginning to wish I had bought the mock three program instead thanks for any help

Configure the machine in inches.

Here is a copy and paste from part of the UCCNC user manual:

Homing speed up: Which is a numeric value and sets the feedrate of the motion when homing the
axis and when the axis is moving to the home sensor.
The Homing feedrate can be equal or lower than the Velocity parameter of the axis.
The parameter is defined in Units per minute.

Homing speed down: Which is a numeric value and sets the feedrate of the motion when homing
the axis and when the axis is moving down from the home sensor.
The Homing feedrate can be equal or lower than the Velocity parameter of the axis.
The parameter is defined in Units per minute.

Write offset on Homing: Which is a numeric value and sets the coordinate to write to the axis
position DRO when a homing action is executed and succeded.
The parameter is defined in Units.

The homing position DRO value can be autoset with checking the checkbox next to the field.
If the autoset checkbox is not set then the axis will remain it's coordinate when a homing sequence
is successfully executed. If the autoset checkbox is not set then the set value will be written to the
axis position DRO when a homing sequence is successfully executed.
Back off: Which is a numeric value and is a movement distance the machine axis will make after
the homing off. If the parameter is set to 0 then no movement will happen after the homing.
The movement can be to the negative or positive direction depending on the sign of the value.
The final position after the back off movement is registered as the home position.

Steps per Units: Which is a numeric value and means the output pulses per one Unit of mechanical
travel on the machine axis. The correct value depends on the resolution of the motor and motor
drive in case a stepper motor and drive is used or on the encoder resolution if a servo motor and
drive is used to drive the axis.

Velocity: Which is a numeric value and sets the maximum feedrate on the axis. The axis cannot run
on higher feedrate then the set value. In G0 (rapid linear motion) code execution the motion is
executed with this feedrate value.
The value of this parameter is in Units/minute.

Acceleration: Which is a numeric value and sets the maximum acceleration value of the axis. The
axis cannot accelerate faster than the set value.
The value of this parameter is in Units/sec/sec.

Softlimit - : Which is a numeric value and is the negative direction software position limit. The axis
cannot run to a lower coordinate than the set value. Note: The software limits can be enabled or
disabled on the general config tab page with checking or unchecking the enable softlimits
checkbox.
The value of this parameter is in Units.

Softlimit + : Which is a numeric value and is the positive direction software position limit. The axis
cannot run to a higher coordinate than the set value. Note: The software limits can be enabled or
disabled on the general config tab page with checking or unchecking the 'enable softlimits'
checkbox.
The value of this parameter is in Units.

Backlash distance: Which is a numeric value and sets the backlash distance to compensate on the
axis. The backlash compensation can be enabled or disabled with checking or unchecking the
'enable backlash' checkbox next to the textfield.
The value of this parameter is in Units.

Compensation acceleration: Which is a numeric value and defines the acceleration of the axis
when compensating the backlash and also used when rigid tapping (G33.1 and G33.2) and when
thread cutting (G33 and G76). This value has to be set at least 20% higher than the acceleration
parameter of the axis.
The value of this parameter is in Units/sec/sec.

So you set up UCCNC in whatever units you use. If you set it up with mm units but then bring in a gcode file which was processed in inches, your cut part will be all wrong.

In mach3, we have mach3loader, so that we can configure mach3mil1 in mm, mach3mill2 in inch. How about in UCCNC, is there anything like this ?

[laki]

Just create 2 profiles, first for mm and the second for inch.

[asuratman]

How to save 2 different profiles ? I open 1 uccnc then make 1 profile in mm, save it automatically when you configure uccnc. I open again uccnc, configure in inch, then it is save automatically. I will lost my mm profile. So let me know how to do it.

[laki]

Go to settings, profiles and create new profile for mm. Then create another profile for inch. You can also create shortcut on desktop for profiles.

[asuratman]

Txs, from Config then profile.

[Vance]

Txs, from Config then profile.

As far as I know, there is no auto-config translator that takes your imperial unit and translates it to millimeter units or vs versa. It would be inexpensive to do and a slick, high profile marketing challenge to the rest of the planet, but it's not common in this or other motion controllers - that I have used.

You are not starting from scratch, you have the working settings in one profile, just create another and hand move the data or complete it like you did your initial profile.

Your duplicate profiles are just text files on your hard drive so no overwriting them.
