Actually, I changed and looked in Configuration.h many times, and this is the first time that I notice this ! I was thinking that the change would have to be done in MarlinSerial.h, because it has also settings for Serial port. anyway, thanks for your helpful response.by mamech - Firmware - Marlin
thank you so much! but how to change serial port in my firmware.? which part should be edited??by mamech - Firmware - Marlin
Hello I want to use Serial1, Serial2, Serial3 instead of Serial0 in Arduino mega. I want to send the serial communication bytes to the serial pins directly, not using USB. any suggestions about how this can be applied?by mamech - Firmware - Marlin
thank you so much, your information was very helpful! regarding modification in plug in , I did as you said, and it seemd logical also to me, but it did not work and still the output does not change. anyway, it is not a big problem. the hard part is already done! thank you againby mamech - Firmware - Marlin
another point. I remembered why I was using the old plug in. It was dedicated for generating G code that can be read with repetier. I tried the laser plugin that you sent me, and I generated a simple output of 3 squares drawing: M107 S0 G90 G21 G1 F3000 G1 X45.9619 Y81.4413 G4 P0 M106 S255 G4 P0 G1 F100.000000 G1 X105.6317 Y81.4413 G1 X105.6317 Y41.1238 G1 X45.9619 Y41.1238 G1 X45.9619 Y81by mamech - Firmware - Marlin
I do not remember from where I downloaded the plugin, but it seems that what I have in an older version of the plugin that you sent me of jtechphotonics. the plugin that I have does not have "Laser On Command", and "Laser Off Command" text area. so if I understand well now, I will need to connect the laser head to fan output, and in th plugin I will make the on command is M106 S255 and off comby mamech - Firmware - Marlin
hello I found a plugin for inkscape that enables the user from generating a code for laser cutter that can be read by repetier. I drew a square and I generated this simple code: M452 M3 S255 G90 G21 G0 F1500 G0 X47.5746 Y229.8095 G0 F100.000000 G1 X157.2381 Y229.8095 G1 X157.2381 Y133.0476 G1 X47.5746 Y133.0476 G1 X47.5746 Y229.8095 G0 F1500 G91 G90 M5 S0 G0 X0 Y0 M18 my question is, if Iby mamech - Firmware - Marlin
thank you , good information to know!by mamech - Stepper Motors, Servo Motors, DC Motors
thanks for replying. but I want to ask, Why in stand still, there are sometimes noise, and other times no noise? If I understand correctly, if the motor has no noise at standstill, this means that the driver is idle and consumes no current and will not heat up, also this means less heating to the motor , is this true? is is a bug in marlin code? why sometimes there is noise and other times no?by mamech - Stepper Motors, Servo Motors, DC Motors
hello I am new to the world of 3 printers. I tried to use ramps with arduino and marlin firmware, and I began to give a command in manual mode to one of steppers. I tried both repetier host and pronterface. I used my multimeter to see the current that one of phases of the stepper will draw. I found that, the motor nearly does not draw significant current while rotation, and it usually draws a sby mamech - Stepper Motors, Servo Motors, DC Motors
hello I am trying to move manually the steppers from repetier or pronterface. I could move them successfully, but I noticed that when I move an axis from the software to move 10 and then -10 (for example) I found that motor does not return to same place. I notice that motors moves in a direction more than the opposite direction. I tried to play with pots of current limiter in stepper driver witby mamech - RAMPS Electronics
yes, I discovered that I am using wrong marlin software dedicated to delta machines.by mamech - RAMPS Electronics
Quotejatmega Hi It would really help if you could attach the marlin files configuration.h and configuration_adv.h, and a picture of the motor wiring to the ramps board. That way it will be a lot easier to troubleshoot it. Can you describe more in detail how you manually moved the axis? like step by step menu selection on the 3D-printer. Hope we can solve this jatmega thank you very much for yoby mamech - RAMPS Electronics
thanks for reply, I checked, and Corexy is already commented.... so I do not know what is the cause of this problemby mamech - RAMPS Electronics
hello I am totally new to the world of 3d printers. I have ramps 1.4 and I have marlin firmware. my first 3d printer is something called "e-waste" 3d printer, it is based on steppers gotten from old CD-roms and floppy. as kind of testing the concept, I made connections for only 2 motors with ramps X axis and Y axis. I tested that my connection is working fine when by testing them by ramps1.4by mamech - RAMPS Electronics
