That looks quite a bit better than what you had before.

I may be going about it wrong but in the short time I have been printing the best indicator of temp is to print something that is thin wall with no infill 1-2 layers thick then break it and check for...

I just leave the diameter set to nominal and adjust the flow rate multiplier for each roll of filament I use. So when I start a new roll I print the calibration cube at 100% infill and adjust the...

Sent you some files.

I am not sure, looks like those prints may be a bit too hot but I run ABS@ ~245-250 otherwise I don't get good layer adhesion so if those are at 230 I wouldn't think they would be hot. If you pm me...

Are you still having to mess with your home position before every print? Did you ever upgrade your firmware or change the Z home axis feedrate?

How are you zeroing out the nozzle in the middle?

What material and temperature are you running?

What program are you using to slice with?

Have you checked the nozzle height in the middle of the bed after you home it?

Do you have a picture of the part you printed?

Yep you have to make sure the machine is going to the same home position everytime you home it otherwise you are shooting a moving target

A few more things for you,

1. I have not used Cura but I know with slicer you can set a Z offset position, the offset is applied to the Gcode when it is generated and adjusts all the Z positions...

I think you would be better off printing some calibration objects instead of actual parts. That way you can follow a guide on what you need to do to improve the parts and calibration of your...

The homing feed rate is in the configuration.h file

Also Colin already has the updated firmware uploaded. Here is the link to download it.

Yes, search for HOMING_FEEDRATE and you will find it.

Happy to say that my homing issues are now solved, I have printed about 4 prints and have not had to mess with homing at all. Normally I would...

I heard back from Colin regarding the speed setting in the config file. It looks like this was our problem, here is what Colin replied.

The Ramps config is different here are the values from it.

#define HOMING_FEEDRATE {50*60, 50*60, 50, 0}

Maybe this is the issue that people are having? Would that be .883 mm/sec?

I sent an...

Yes that was directly from the config file that I downloaded for the Rumba from makerfarm.

I am going to download the rambo firmware from makerfarm and look at it. I have run into a few...

Unless I am mistaken this is the home feedrates from the config file.

#define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0}

that is the X, Y, Z, extruder rates, in that order.

There are at least a...

After reading this and some searching it appears that a lot of people have issues with the default homing speed. Most say changing it from 4 to 3 takes care of the problem. I am about to upload the...

Never mind, I found it.

Where do you adjust the speed that the Z axis homes at for the final home? Can't seem to find it in the config files.

I originally used the Zip ties but changed to bolts after I had issues with Homing.

What were your print settings for that print? Looks like you are over extruding.

My print quality is good when I am not screwing around with the homing issue. It is hard to say what the print quality issue is without actually seeing the part in hand. I am sure you posted it...

I am also having Z homing issues with the 12" that I put together 1-2 weeks ago. I have swapped the Z axis home switch around with one of the others and have everything mounted with screws. It is...
