Hi Tim, The problem we had yesterday was 500mm was corrected by 3mm as there was 503mm in the file but then at !000mm where we had 1000mm in the file and no correction there was still an error of at least 3mm, the error never interpolated back to zero error. That makes perfect sense as the first gri...

Hi Tim, Attached is an equivalent test Geocorrection file in inches. Here is a Patch for Version 5.4.1 to allow changing MaxCorrPerIteration by a parameter in Kinematics.txt file. Copy attached Kinematics.txt file to \Kmotion5.4.1\KMotion\Data folder which sets the increment to 100 inches. 100 incre...

Hi Tim, It is possible to do a single axis type of “screw mapping” as described in the wiki here . But your method should work also. The mapping file is only supported in inches so you would need to convert all the coordinates to inches. But even so the 503/500 scaling would initially be the same. Y...

Hi ADUFF, That all seems possible. KFLOP doesn’t have hardware I2C and I2C is difficult to do in software unlike SPI. I not familiar with UART to I2C converters. Consider using our Kogna Controller which has hardware I2C. It would also likely eliminate the need for a Kanalog. This shows a simple Kog...

Cool. From your 23.6,23.6 position you might move 1 inch to the right 24.7,23.6 and check the motor angles on the KMotion Axis Screen as well as measuring the physical movement to try to determine what’s wrong. Then do similar in Y.

Including your .h file is the correct way to define the class. The problem is that DanasScara contains the term Scara and it checks for Scara first and finds it. Reverse the order of the checks to check for the more specific case DanasScara first and it should select yours. We should probably do an ...

Its not necessary. That file is used by the GCode Screen in KMotion.exe which is obsolete and replaced by the KMotionCNC Program.

Hi Dana, After reading your reply I first moved the arms inline and along something close to an x axis. Then I set the postion of the end (47,0) I'm not sure what you mean by "set". If you mean the 'Set' buttons in KMotionCNC that wouldn't be correct. Those set GCode offsets. The Kinematics operate ...

Hi Dana, Jogging with non-linear kinematics is actually somewhat more complex than coordinated motion because it can start/stop/change direction unpredictably unlike coordinated motion that can be pre-planned. Let's get the homing sorted out and see how it moves. I think the axes should homed in a w...

Hi Tim, on Fed hold two sets of arrows are displayed. Where do they come from and how can i remove them please ? This is a powerful feature of KMotionCNC which is the ability to move forward and backward along the GCode Path while in Feed Hold. They automatically become visible while in Feed Hold. W...
