Re: Adding linear encoders for higher positioning accuracy

Hi Tom, I'm happy that there is a solution for it. I'm going to give a go for one axis first. It will take me some time to get this installed. As far I understand loop tuning will be carried out as normal for rotary encoder as it is now - no change ? Having this C code running my DRO reading will sh...

Re: Adding linear encoders for higher positioning accuracy

Hi Tom,

Thank you for answer
I agree that two encoders will give better control stability,

unfortunately these motor drives have no option to work in fully closed loop. they are Estun PRONET 17-bit resolution.

Adding linear encoders for higher positioning accuracy

Hello Tom, I have a heavy and stable 3-axis machine for tool machining that has been operating on the KFLOP platform for several years. Three servos and the spindle are configured for control via DAC. The time has come to involve optical linear encoders with a final resolution of 1um. Before I stop ...

Re: Rigid Taping - DAC closed loop Spindle

Hi Tom, Still not good, This time program starts tapping but virtual thread over the material. It's mean starts cycle from CCW Spindle rotation and Z axis going in positive direction. Also Console buffer loops up gathering lot of data even after killing threads and Reboot! command. To get out from t...

Re: Rigid Taping - DAC closed loop Spindle

Hello Tom, I think I know what is going on, but I'm not able to fix this bug, I'm working on RawMAchineCoordinates OFF, XYZ are set to Gcode value, everything is positioning to proper distance a part of Z parameter in G84. For example: - having code G84 Z-6 R2 Q4 F1.5 machine will go to Z-6mm but in...

Re: Rigid Taping - DAC closed loop Spindle

Where is the Z axis coordinate before the Tap? Z coordinate goes to Z2 over the hole and moves from hole to hole on the same high and finishes program on Z2 as well. What GCode are you running? (Call a Rigid Tap Sequence) G21 F1000 S200 G1 X40 Y40 M7 G1 Z5 G99 G84 Z-6 R2 Q4 F1.5 X0 Y0 X60 Y70 G80 G...

Re: Rigid Taping - DAC closed loop Spindle

Hi Tom, I've got new issue regarding Gigid Tapping, kflop version 4.35f I discovered that my Homing code Inhibits Rigid Tapping routine. After INI machine, without homing, Rigid Tapping works, all the time for whole day... After INI machine and making homing procedure, Rigid Tapping is invoked by M1...
