- CORR_STRATEGY_REMOVE_SMALL_ARCS (0x00200000):
After tool compensation calculation, there could be arcs with negative or very small radius. If the calculated radius of such arcs is smaller than a value given in GCODE_PARAMETERS::tolerance[GCODE_MINIMAL_ALLOWED_ARC_R], the arc will be removed. This bit is usually set.
- CORR_STRATEGY_NO_ADD_R (0x00400000):

| Index to array | Used for movement |
| 0 | fastfeed (G0) |
| 1 | forward (G1, G2, G3) |
| 2 | backward |
| 3 | connect |
| 4 | speed of forward motion without M function (regime 31 of function ToolChainCore_StartCNCEx) |
| 5 | feed in function ToolChainCore_GoToPosition |

| 7 | deceleration for emergency stop, only dec field |
Definition at line 1430 of file TGM_CNC.h.
◆ correction

| 2 | G43 |
| 3 | G44 |
| 4 | G45 |
| 5 | G46 |

Definition at line 1443 of file TGM_CNC.h.
◆ maxConnectionDistance
| double GCODE_PARAMETERS::maxConnectionDistance |
Maximum distance from given point to the trajectory for ToolChainCore_ConnectCNCEx_Plane. If the distance from the trajectory part is greater, this part is not used for calculation of the connection point.
Definition at line 1456 of file TGM_CNC.h.
◆ startAngle
| double GCODE_PARAMETERS::startAngle |
The two parts in the G-code can follow each other tangentially or with some angle. If the angle is small enough the system can move through with any deceleration. The threshold is given by this value in degrees. If the mutual angle of the two parts is larger, the system decelerates up to minAngleFeed, depending on the endAngle value.
Definition at line 1460 of file TGM_CNC.h.
◆ endAngle
| double GCODE_PARAMETERS::endAngle |
If the mutual angle of two parts of G-code is larger than this value, the system slows down to the feed defined in minAngleFeed. Values between startAngle and endAngle are interpolated.
Definition at line 1466 of file TGM_CNC.h.
◆ minAngleFeed
| double GCODE_PARAMETERS::minAngleFeed |
Minimum feed for motion if the mutual angle of two sections is greater than endAngle. Can be set to zero, in which case the system stops between two parts (with the mutual angle larger than endAngle)
Definition at line 1470 of file TGM_CNC.h.
◆ disableG0FeedOverride
| int32_t GCODE_PARAMETERS::disableG0FeedOverride |
If equal to 1, then the interpolator ignores feed override during fastfeed. Also enables automatic stop between two G0.
Definition at line 1474 of file TGM_CNC.h.
◆ interpolatorConfig0
| int32_t GCODE_PARAMETERS::interpolatorConfig0 |
Bit coded value for change the interpolator behavior. Only bit 0 is used. Other bits are reserved for future use.
- bit 0:
- 0 - relative speed is changed only during achieved speed (i.e. during the acceleration or deceleration, the ToolChainCore_SetRelFeed is not active and the change is performed only after the full speed is reached)
- 1 - relative speed change by time quantum, i.e. function ToolChainCore_SetRelFeed changes the speed immediatelly. Note that ToolChainCore_SetRelFeed than changes the acceleration and deceleration as well.
Definition at line 1477 of file TGM_CNC.h.
◆ overrideInc
| double GCODE_PARAMETERS::overrideInc |
Increment of feed override at 100us time slice. When the relative speed is changed by ToolChainCore_SetRelFeed, it cannot be done immediatley, but smoothly with a ramp. This value describes how fast the relative speed will be chnaged from one value to other.
Maximum is 0.1 = 10%
If equals 0, default value 0.001 is used, i.e. 0,1%.
Definition at line 1484 of file TGM_CNC.h.
◆ arcFeedTable
Table of relative speeds in relation to arc radius, 5 pairs all together [radius; rel_speed]. Zero radius value in the table means that the remaining values are not used, i.e. the table can have 0 - 5 items.
Examples:
- all values set to zero - table is not used (default)
- arcFeedTable[0].m_r = 0, arcFeedTable[0].m_relFeed = 0.5
all arcs are run by relative speed of 50% (50% of the required arc speed)
- arcFeedTable[0].m_r = 10, arcFeedTable[0].m_relFeed = 1.25,
arcFeedTable[1].m_r = 0.9, arcFeedTable[1].m_relFeed = 0.1
arcs with radius >= 10 (R=10) will have relative speed 125%, arcs smaller than R=10 up to R=0.9 will gradually have decreasing speeds up to 10% and all arcs smaller than R=0.9 will have 10% relative speed
Definition at line 1491 of file TGM_CNC.h.
◆ mFuncInsertTable
automatic insertion of continuous M functions to signal decrease in speed or reaching cutting speed.
| table index | description |
| 0 | M function before deceleration on arc - signalling future deceleration. If mFuncInsertTable[0].mFunc = 0, signalling is not used. |
| 1 | M function before acceleration on arc - signalling future full cutting speed. If mFuncInsertTable[1].mFunc = 0, signalling is not used. |
| 2 | M function before fastfeed G00. If mFuncInsertTable[2].mFunc = 0, signalling is not used. |
