  • i added a handling for S commands, works in repetier protocol, but still get format error in ascii protocol... cannot see the trap, ist there something wrong in ascii parsing? void Commands::processSCode(GCode *com) { uint32_t codenum; //throw a…
  • but with repetier protocol i get : 22:19:07.496 : Error:Checksum required when switching back to ASCII protocol. when using buttons assigned to   case UI_ACTION_X_ZERO:             if(!allowMoves) return UI_ACTION_X_ZERO;             GCode::execut…
  • Ok, skipping commands just happens in ASCII protocol. see snippet from LOG using Ascii protocol: 17:55:20.874 : N24 M117 ETE 3m 04s *111 17:55:20.874 : N25 M105 *48 17:55:20.874 : N26 G1 Y155.5 *111 17:55:20.874 : N27 G1 X294 *122 17:55:20.874 : N…
  • Hi,are your Extruder Motors all the same? and Drivers adjusted matching to the Motor specs?had such an issue with the DRV8825 on Ramps Long time ago.
  • sent it by Repetier host,Printer mode CNC, and yes, the S1000 was ignored .My Problem is , that the move following the S1000 was not executed and this is reproducable.didn´t check it with a M117, but i´ll try thatwill post code and log this evening …
  • Ok,thanks.I´ll try to reduce the Gcode above to a part of just one circle to see if that still happens.Hope i´ll find the time to investigate next week. another finding regarding G-code handling (killed some flutes yesterday):Cambam adds some single…
  • didn´t define that, only found it in motion.cpp #ifdef REDUCE_ON_SMALL_SEGMENTS    what about jerk?  i have jerk 7.0 cannot go higher because my moving table´s weight is around 12Kg. if i increase jerk it´s like an earthquake... another quest…
  • seems to happen illogical using cambam gcode with G3 circles everything is ok also circles by G1 lines. here´s a snippet from gcode where that slow down happens(extruder is commented, feedrate set to 2400mm/min) : Gcode is generated by slic3r , a…
  • buffer size is 40 , also tried 80. i do the test with circles , thats right, but on turnover point machine nearly stops. if i set backlash values to 0 it runs absolutely smooth. as soon as i put a value (in my case i need 0.005mm  to 0.009) it slows…
  • What´s the implemented version of changing intensity at the moment? i mean G-Code style: i just found by M3 S...     or is it even possible by G1 S...?(some CAM software does this style) other style i found  is switching on by M106 S... /off by M1…

  • Switch off time should go ->0 it can just depend on capacitors in Laser Driver.Laser current is 2.4 A and Cap is quite small so there is no chance for Switch off delay.I think the 14ms base on a kind of softstart to prevent from current overshoot…

  • changed it matching to your proposal ,can be easily adjusted now using Repetier Host with enough precision think you should  generally change this  in firmware to show that number of digits ,i cannot imagine to be the only one trying to fine adjust…
  • As Photodiode arrived now i did the measurement with Laser Power up. Result shows 14 to 16 milliseconds to start Laser by Power ON/OFF My warmup time i found experimental is 200 milliseconds  so Laser Power UP  is minor part of needed time. will t…

  • OK,Thanks for information
  • you should set motor current matching to motor specs...don´t adjust by a "feeling" that cannot work. refer pololu datasheet regarding reference voltage and motor specs also. i don´t know your motors , but if they are in parallel connection on one dr…
  • so in may case i dont have a pwm input, i just can switch power on and off thats why i think that causes major part of delay. I got a modification instruction from dtrlpf today (i use the x-drive driver from them)to have a pwm pin. will try that an…

  • ok, will think it over , my actual priority is still the laser stuff , so i won´t start immediate ;-) anyway , have a simple solution running for myself to avoid writing lots of ui-actions during my tests but momentarily it´s just ugly breadboard st…

  • may be i´m wrong regarding the reason for the delay, part of it seems to come from laser driver during power up and should be nearly constant.another part is the time material needs to heat up and start burning. ordered a photodiode now (photoresis…

  • well,we could also implement a i2c version for the users which want buttons but have no pins free . i know we already have possibility in ui but i think macros should be independent from ui. so it depends on user if using ui_action or g-code macro. …

  • I try to understand what you´re doing so why don´t you add an external pulse generator to the laser output? means pulses start/stop  is triggered by laseron/off . pulses generated by for example CD4047 or if you want to change pulse/pause separately…
  • to get setup against focus i think it´s square function based on power/area. so i think  it will stay a very individual setup depending on laser Type, wavelenght,emitted power and material. for a cw laser diode (which i think are most popular in our…

  • saw that , thanks!!
  • you´ll not see an quadstepping issue on homing speed when quadstepping starts depends on feedrate and steps/mm  and will be active for higher speeds only. i think it will be active during combined x/y moves for example : after homing  send a G1 x2…
  • just try if quadstepping works, so i think the settings you have are ok with. STEPPER_HIGH_DELAY 1 DOUBLE_STEP_DELAY 2 if it works, keep them... may be you can reduce double step delay to 1 , but i wouldn´t do it if quadstepping 1   may be you hav…
  • Here you can see the difference: upper : without wait time lower : 200ms wait before firstmove had to add it to G2/G3 also ,now it´s great engraving result 3W blue Laser , feedrate 400mm/min  linewidth 0.1mm material :Formica / Resopal diffe…

  • can you please write something about your experience with this hotend? I´m very interested. Kind regards, RAyWB
  • Ok, it´s working now without buffer running empty , detect first move and laser switched on with added delay before first move :-) so now i want to add the delaytime to eeprom to get it easily modified during operation , as it strongly depends on m…

  • no you wont burn something . you just slow down the pulses a bit. in your case to find the problem i´ll try first ALLOW_QUADSTEPPING 0  what just means you disable quadstepping and STEPPER_HIGH_DELAY 2 DOUBLE_STEP_DELAY 3 if that works you can sp…
  • so you should have endstop at z-max. set #define min_software_endstop_z false
  • If you have DRV8825 drivers try these settings. Sound comes from stalling motors #define STEPPER_HIGH_DELAY 1  //or 2 if you operate from 12V supply 1 should work on 24V #define DOUBLE_STEP_DELAY 3 // time in microseconds #define MAX_ACCELERATIO…
