Jogging with analogue joysticks is available now on myCNC control software.
2012.02.06 12:46:10

 

2 or 3 axes analogue joystick can be connected through ADC channels of myCNC-ET1 controller and programmed for pendant panel jog  motion. Motion speed is smoothly regulated with about 1% accuracy.

We are working also on MPG (Manual pulse generator) support for myCNC software.

Fanuc-style Macro programming: G65 code implementation.
2011.12.07 12:12:58

G65 code implementation

 

We are working on G65 code implementation which allow to work with parameterized macros. G65 code runs macro program with number, programmed in P parameter.
Up to 21 local variables could be sent to the macro through A-Z parameters.

In a screenshot is shown peck drilling cycle (G83) repeated in a line by running G65 with macro O9911.
Number of drills is programmed by H parameter; distance between drills programmed by U parameter; line angle angle programmed by A parameter.

 

Listing of nc program is below:

%
(XY - position)
(U - distance between points)
(A - angle)
(H - number of points)

G83 Z-10 Q2. R0.5 L0
G65 P9911 X10 Y20 A30 U10 H5

G68/G69 codes works now with planes codes G17,G18,G19
2011.11.24 11:20:11
G68/G69 codes works now with planes codes G17,G18,G19 for myCNC software.

(Described features will be available in myCNC control software version 1.72)

Rotation coordinates codes G68-G69 may be used now with planes codes G17-G19 to rotate coordinates in any of planes XY, XZ, YZ.

On a picture below there is a sample of using G68/G69 codes with G17-G19 plane selection. Also in the sample was used parameterized programming and M98/M99 subroutines (subprograms).

Automatic gas console implementation through PLC layer of myCNC-ET1 controller.
2011.11.21 12:37:13

Great sample of using built-in PLC controller is implementation of Automatic gas console control for oxyfuel gas metal cutting.
Automatic gas controle may work under myCNC control software control or as independent unit managed through serial RS485
comminication (Modbus ascii protocol). Aitomatic gas controle control all oxy cutting technology (automatic ignition, forced preheat,
piercing with smooth oxy cutting growth, cutting, after cut soft flame.

Gases pressure for fuel, preheat and cutting oxygene controlled electronically by 3 PID controllers, integrated in myCNC-ET1.

myCNC based mill machine demo.
2011.11.21 12:10:58

This is our 3 axes mill machine based on myCNC (myCNC-ET1 LAN CNC controller, myCNC software, 4x myServo-A01 servo drivers).
NC program was written by manual so tool path is far away from optimal. Cutting speed is 1m/min. Spindle speed is 24000rpm.

We have NURBS implementation in myCNC now.
2011.06.09 06:29:47

We have implemented NURBS (Non uniformed rational B-spline) in myCNC software and myCNC controllers.

It worked now in test mode. G-codes G5.2 & G5.3 describe NURBS control points. myCNC control software decomposes NURBS to bezier spline curves and sends it to myCNC controller. Complete 3D spline interpolation iterration inside myCNC controller takes about 30us. With 80us of processing time it's about 40% of CPU time which is reliable for stable work.

We have tested NURBS with Butterfly sample from EMC2.
