Rep.FW: H-bot setting not working for 1 extruder - 11 years ago
Hi, I am observing a strange behavior with the latest release of Repetier Firmware (ver. 0.91): I have an H-bot (DRIVE_SYSTEM=1), and 2 extruders (NUM_EXTRUDERS=2). This configuration works fine so far. Now, after changing just NUM_EXTRUDERS=2 to NUM_EXTRUDERS=1 (ceteris paribus), and uploading the firmware to my Megatronics v2.0, I observe that my coordinate system is shifted 45deg.

Re: Update on the E3D All Metal Hotend (Now finally shipping!) [Lots of pictures] - 11 years ago
I did notice these claims. However, they represent narrow claims. In Patents, I believe that the general claims are more important, ... at least to my knowledge of reading patents. I.e. Claim (1) in this case would fit well into what the E3D design achieves with a thermal break between the hot-end and the cold-end (heatsink): 1.

Hi, I am thinking about using the famous E3D hotend in a new printer design that I am working on. The reviews are amazing - I am convinced that it is truly the best hot-end out there - good job! Nevertheless, in light of the recent patent infringement case in the US, I am worried whether the E3D design potentially infringes on the thin-tube liquifier patent: Patent US6004124 I am aware that itby andin - General

Re: RF: Prevent the start of print-job until... - 12 years ago
Thanks for the clarification! If I look into the code, the objective of the method readFromSerial() is to make sure that the serial buffer gets filled with GCode commands from the host. These commands are then processed using: GCode *code = GCode::peekCurrentCommand(); ... if(code) {... Commands::executeGCode(code); code->popCurrentCommand(); } inside the void Commands::commandLoop()by andin - Repetier
Re: RF: Prevent the start of print-job until... - 12 years ago
Ok, as far as I understand the function void GCode::readFromSerial() takes the commands from the controller's serial buffer and translates them into action. If I prevent the controller from processing the buffer by blocking the above function during an active print-job, the buffer of the controller will get full - the controller will thus report this to the host - the host will therefore not senby andin - Repetier

Possible firmware's requests to Repetier Host - 12 years ago
Hi, I noticed from another thread that the Repetier Firmware can send a pause request to the Repetier Host: OUT_P_LN("RequestPause:"); This is a very very useful feature! Are there any other similar requests/commands that one can send to the Repetier Host? It would be helpful to know these in order to explore the possibilities.by andin - Repetier

I am thinking about implementing a door to my 3D printer with a micro-switch which detects whether the door is closed or open.

Re: Using Serial3 with Repetier Firmware - 12 years ago
So how does the hijacked library improve the printer performance overall? Does it allow faster printing speeds since the printer can receive more commands per unit time? Does it reduce the communication errors? Sorry for being insistive- I am trying to understand. Thanks.by andin - Repetier
Re: Using Serial3 with Repetier Firmware - 12 years ago
Ok, if the serial 2-5 were removed from hijacked library, than there is really no way of using it with the display since one would need at least two serial ports (serial1 for PC and serial 2 for display). I guess this is bad news for the touchscreen. Compromising communication speed for the ability to use the touchscreen is not a desirable option.

Re: Using Serial3 with Repetier Firmware - 12 years ago
Does this mean that the Serial 1 will also use the original Arduino library if I define: #define EXTERNALSERIAL // Force using arduino serial ? Or would it be that the communication with the PC (GCode commands) will still perform over serial 1 using the hijacked library, while any other serial interfaces (e.g. display) will use the original Arduino library? Is there a way around this? For examby andin - Repetier

Hi, Can I safely use gcode_execute_PString(PGM_P cmd); to place Gcode commands into the command buffer while printing? For example, I want to home X-axis during print. After homing, the print should continue. From repetier-Host, this is easily done manually: just enter "G28 X" during print. Now, is it possible to do the same safely from the Repetier firmware, e.g. like this: gcode_execute_PStrby andin - Repetier

Re: Repetier Firmware: set a flag when the extruder motor is turning - 12 years ago
This looks interesting. the void isEMove() is not present in the current released version. Is there a chance to get this job done in the current version - maybe by polling some variables or integrating a routine that sets a flag inside an ISR of an extruder stepper?

Re: Repetier Firmware: h-gantry + steps-per-mm - 12 years ago
I appologize for my last post - it was intended as an answer to another question in another forum. The problem with the X/Y movement was indeed related to EEPROM settings, and to MAX_LENGTH in particular. I have checked EEPROM settings again, and these were messed up for some reason (0 or 255 values for some of parameters). After uploading the firmware again, the problem was solved.

Repetier Firmware: set a flag when the extruder motor is turning - 12 years ago
Hi, I am trying to find a way to set/reset a flag-variable when the extruder-stepper turns/stops, using Repetier Firmware. In other words, I am trying to make an LED lighten up when the extruder is extruding, and turn it back off when the extruder is not extruding. This seems to be not such an easy task!

Re: Repetier Firmware: h-gantry + steps-per-mm - 12 years ago

Thanks, MAX_LENGTH values are correct. The device is homed with at x_max and y_min. The same problem persists even for G1 X10 or G1 Y10. EEPROM_MODE is set to 1. I can change EEPROM constants in Repetier-Host and this works. Where else could the problem be?by andin - Repetier
Re: Repetier Firmware: h-gantry + steps-per-mm - 12 years ago

Hi, I am testing a classical h-bot gantry with the Repetier-Firmware. So far, the movement direction and the endstops are working fine. However, the movement distance along the X and Y axis is not correct: eg. command G1 X200 makes the extruder move only around +170mm in the X-direction. G1 Y200 moves the extruder only around +170mm in the Y-direction. Settings (double checked in EEPROM): XAXby andin - Repetier
