To multiply your current movement distances by a factor of 3 then go to Config / Motor Tuning and multiply the ‘Steps per’ by 3. Do this for each axis clicking ‘Save Axis Settings’ after each change.
As an alternative you could go to the Settings page and use the Axis Calibration feature to set the correct steps per unit for each axis.
The recommended method is to have two drivers (one for each motor). One will be the Y axis and the other will be the A, B, or C axis (you can choose) and these two axes are slaved together within Mach3 setup. For more details the Mach3 manual has information with regard to slaving two axes and homing (squaring the gantry). http://www.machsupport.com/help-learning/product-manuals/
This is an example of what I think you want to achieve...
Initially a logo is found which is close to the required size (internet search). The logo is then converted to a .dxf and scaled to the desired size (cad software). A Gcode toolpath is generated from the .dxf (cam software).
It has a background size of 23.8 x 13.2 mm and when scaled up to the required 90 x 50 mm has such poor resolution that it would be unlikely to yield any i and j arcs.
Try to find something of the correct size and of a good resolution.
(You could use a CAD software to create a border 90 x 50 mm then perhaps insert some text with a font that contains arcs - the easiest solution perhaps).
You have to do some of the work yourself - I have no intention of doing it all.
1) Find (or design) a logo of the correct size, containing the required arcs (.bmp would be OK but .dxf preferred). 2) Use the full reply and additional options tabs to post your logo here.
I will convert it into a dxf and produce an engraving toolpath Gcode then post both here for you.
