Acramatic 2100 Fusion360 Post Processor

Rework of the existing vickers/autodesk provided post-processor. Vickers - you can absolutely use this instead of yours :D

Added support for spindle probing, tool probing and rotary 4th A axis.

TODO:

• Fix probing math to accurately update the WCS - some are right, some aren't - watch IJK values in probing ops
• G51 vector probe for WCS G51 doesn't set coordinates (release 2 limit/bug?)
• improve tool probing to use correct P word for tool type automatically
• remove hardcode rigid tapping and use post processor option to support both tap types
• add support for tool wear updates via probing

CNCZone forum is full of excellent help for these. gwood is the GOAT

Probing G-code

• G75 internal corner
• G76 external corner
• G77 locate surface
• G78 bore or boss
• G79 pocket or web
• G51 vector probe

Tooling G-code

• G68 set tool size
• G69 check tool size

Probe Cycle Parameter Table (pg 380)

cycle	program reference	range	usage
Probe Approach Feed rate	PRB_APPR_FRT	0 to 999in	Specifies probe approach feed rate for first probe contact
Dimensions Probe measurement feed rate	PRB_MEAS_FRT	0 to 999in	Specifies probe approach feed rate on a second measurement move following the initial hit. This value is selected when the Q word = 0 or absent.
Rotating Tool Retract distance	FIX_PRB_RRET	0 to 99in	Specifies spindle running retract distance following the initial probe hit
Probe Gage Height	PROBE_GH	0 to 9.9in	Specifies retract distance after a probe hit
+X Stylus Tip Dimension	X_POS_TIP	0 to 9.9in	Specifies stylus tip offset for the probe used.
--X Stylus Tip Dimension	X_NEG_TIP	0 to 9.9in	Specifies stylus tip offset for the probe used.
+Y Stylus Tip Dimension	Y_POS_TIP	0 to 9.9in	Specifies stylus tip offset for the probe used.
--Y Stylus Tip Dimension	Y_NEG_TIP	0 to 9.9in	Specifies stylus tip offset for the probe used.
Tram Surface	TRAM_SURFACE	0 to 99in	Reference from machine table surface or fixture. Usually established with precision gage blocks.
Fixed Probe Tram Surface	FIX_PRB_TRAM	0 to 99in	Specifies top position of fixed probe stylus.
Fixed Probe clearance height	PRB_PRB_CLR	0 to 999in	Is the value added to the Probe Tram surface above the top of the Probe

Probe system variables (pg 385)

name	definition	field name	description
[$PRB_DIA_ERR]	Probe Tool Error contains the tool diameter deviation as measured by the fixed probe in a G69 cycle		0 - 99999mm
[$PRB_PART_LOC]	Probe Part Location is the coordinates of the measured part feature for G75--79 probe cycles.	X, Y, Z	0 - 99999mm
[$PROBE_POS_MC]	Location of the most recent probe hit in machine coordinates	X, Y, Z, U, V, W, A, B, C	0 - 99999mm
[$PROBE_POS_PC]	Location of the most recent probe hit in program coordinates	X, Y, Z, U, V, W, A, B, C	0 - 99999mm
[$PRB_TOOL_ERR]	Probe Tool Error contains the tool length deviation as measured by the fixed probe in a G69 cycle		0 - 99999mm
[$PRB_WIDTH]	Measured width of a pocket or web after a G79 probe cycle		0 - 99999mm
[$PRB_A_ANGLE]	Angle between two measured points in the Y axis plane, R word specifies rotary A axis	R
[$PRB_B_ANGLE]	Angle between two measured points in the X axis plane, P word specifies rotary B axis	P
[$PRB_INCL_ANG]	Angle data used by G51.4 and G51.5 for second measurement positioning
[$PRB_X_ANGLE]	Is the computed X axis side of the corner when P word is programmed (G75 and G76)	P
[$PRB_X_DIA]	Measured X axis diameter of a bore or boss after a G78 probe cycle.
[$PRB_Y_ANGLE]	Is the computed Y axis side of the corner when R word is programmed (G75 and G76)		0 - 99999mm
[$PRB_Y_DIA]	Measured Y axis diameter of a bore or boss after a G78 probe cycle	R
[$PROBE_HIT]	Probe Hit is set to true (1) by the G75--79 probe cycles if a probe hit occurs during the probe cycle. Following a probe cycle, this value is true if the probe hit the part and false (0) if no probe hit occurred		0 - 99999mm
[$SIZE_ERROR]	True position value plus tool offset	X, Y, Z
[$TOL_EXCEEDED]	Measured size error exceeds U word value		0 = false, true = 1
[$TOOL_PRB_LOC]	Measured Tool Probe Location	X, Y	0 - 99999mm

install

1. install visual studio & git
2. install fusion 360 post processor editor - https://marketplace.visualstudio.com/items?itemName=Autodesk.hsm-post-processor
3. find posts to use as examples (some are located in this repo already) - https://cam.autodesk.com/hsmposts
4. in visual studio open a project (This one as an example)

run / build / test

1. run (f1) > hsm change post executable - C:\Users\username\AppData\Local\Autodesk\webdeploy\production(id)\Applications\CAM360\post.exe the ID can change on updates! my example is C:\Users\jerem\appdata\local\Autodesk\webdeploy\production\b0c303e70bd97cfdc195adab65922cfeffcb363a\Applications\CAM360\post.exe page 51 section 2-43 in the detail guide below

2. open your CPS file post processor

3. cnc selector -> pick a file (probably milling) or use custom (below)

generate a custom CNC intermediate file by using the visual studio post processor. open the NC file on save and it will point to a DIFFERENT folder with the intermediate file in it.

use that in the cnc selector section of the visual studio plugin - 'custom' section (right click -> import cnc)
