Re: Bed leveling matrix to eeprom - 11 years ago

Thanks guys! The advantages are clear, no excessive wear on the z axis, it moves up and down 18 times when doing a grid probing. The g29 would only have to be done when the prints/ first layers are not good or a bed or nozzle change. Kind of like an inkjet, you don't clean the nozzle before every print. James Daniel, I am using it now with a once a day g29, removed the reset from g28 and it w

Bed leveling matrix to eeprom - 11 years ago

I am trying to get the bed leveling matrix (result from probing) stored in the eeprom, to not have to level before every print. Any ideas.

Re: COMBINE COOLING FANS - 12 years ago

Well, my hotend cooling fan generates quite some airflow, I would use this air to cool the print, if I need only very littel cooling of the print, the fan would be slightly reduced in speed which would still cool the hotend adequately. Thing is, it needs to be controlled by the rambo board

COMBINE COOLING FANS - 12 years ago

Did anyone ever combine an extruder cooling fan with a "print" cooling fan. I would like to use the fan that cools the hotend, to cool the abs/pla when needed. Any suggestions?

LCD Display on Rambo - 12 years ago

I have a Rambo board and a discount lcd display and I cannot get the display to work. I tried it on other rambos from friends and it worked just fine. I did all the firmware settings, only thing I am not sure is the arduiono pins.c file. Since I am using Arduiono 1.0.5, that file does not excist. I tried installing an older arduino version 0023 changed the pins.c file and uploaded the firmware

Re: Ramps1.4 on TAZ - 12 years ago

That is what I tried and yes, that is it. They used a very low acc 500 and xy jerk of 5, increasing to 1000 and 15 did the job. Thanks

Ramps1.4 on TAZ - 12 years ago

I recently built a TAZ and I am using Ramps1.4. All works good, but the arcs show really rough segmentation and the printer is running rough on arcs. Same firmware setting on a smaller prusa is very smooth. What do I need to change. Any suggestions? Found this on adv.h // Arc interpretation settings: #define MM_PER_ARC_SEGMENT 1 #define N_ARC_CORRECTION 25 const int dropsegments=5; //everything

Re: Some motors are holding torque - 13 years ago

The motor didn't do any damage in the morning.. I was just working with wires and the board ( disconnected ) and next time I power up, one driver holds torque. Again, everything other then disabling the motor ( only the x) is working fine...I can print fine, just heats up the motor and driver for no reason when idle.

Re: Some motors are holding torque - 13 years ago

Okay, I got the new drivers and this morning all was good. I had a new enclosure made and had to rewire z and y and when I plug it back in, X driver is holding the motor. Very frustrating, are these drivers so fragile? What could cause this? Thanks

Re: Some motors are holding torque - 13 years ago

I will get some replacement drivers.

Re: Some motors are holding torque - 13 years ago

Well, it all works, I can print, it just doesn't release X and E

Re: Some motors are holding torque - 13 years ago

Realized some other thing, when moving the one axis by hand fast, it tends to hold, almost like a short?

Re: Some motors are holding torque - 13 years ago

I measured them both and I got continuity on one and nothing on the other. Any hints...solders look perfect.

Thanks Miso, Measured that, on one I get continuity on the other nothing

Re: Some motors are holding torque - 13 years ago

It is a Lulzbot , running ramps1.4. M84 disables the two other motors not the (now) x and e. I agree with the pins, but I changed the driver and it is now driver related. Weird thing is, it does everything else just fine. btw. it is all brand new and put together by myself, so there is not pin setup other then ramps and pololu

Re: Some motors are holding torque - 13 years ago

I was wrong, it appears to be the drivers, swapped x and y and now x is holding

by Fri - General

Re: Some motors are holding torque - 13 years ago

I plugged Y into X and it was fine. Swapped x driver to y and it is holding torque right away. So it is either the ramps or firmware.

Re: Some motors are holding torque - 13 years ago

Jamesdanielv, Thanks for your quick response. It's Ramps 1.4 and I will try the 34. The pololus are A4988 It homes fine. Only thing is the Y&E that hold troque right away when powered up.

Some motors are holding torque - 13 years ago

I have a new printer set up and all works great, but I cannot turn off the Y&E motors, they are holding torque. They spin and work when activated, but get hot for nothing when not used. It could be a bad solder or so..any input appreciated..

Re: Marlin Settings - 13 years ago

I found a solution, still doesn't explain what is going on, but it works now. Thanks for the help, hope this helps someone else. Fri

Re: Marlin Settings - 13 years ago

Thanks Man, I will get to the bottom of this and let everyone know, but it is very time consuming and puzzling to say the least. I flashed sprinter and did a M119, in Marlin all three were "L" in Sprinter, x&y are H and only z is L. Could this be a hint?

by Fri - General

Re: Marlin Settings - 13 years ago

Thanks, This would explain the problem with the x axis in Marlin, but how do you explain that I don't have the issue with Sprinter. It only is the x and yes it only does it when the x motor is running and only with bounce. I will give the shielded wire a shot. Where did you get the small connectors to connect the wires to the board?

Re: Marlin Settings - 13 years ago

Well that was the x axis, which is the culprit. The Z is working fine, it is right underneath the right column. Something else, and again it is not consistant. When I tigger it manually and the hold it and hit home, the axis makes a slight move towards the stop and then away, obviously this is not good, since it is depressed, it should move away only. And when I flash sprinter, no problem at al

Re: Marlin Settings - 13 years ago

Here are two pics, one with the x hitting the stop and one in the open position. Thanks

Re: Marlin Settings - 13 years ago

No, I tried G28 and it does the same as when I hit home X or home all in pronterface. Y and Z are fine. Thanks
