There is another workaround. You can still use the new versions of Arduino like 1.6.10.
Rename fpos_t variables in SdBaseFile.h and SdBaseFile.cpp to another name like fpos_t1 and recompile. Problem is in C++ you can not use typedef and struct for the same varibale name.
fpos_t is already defined in stdio.h which is a hardware library file for arduino.

Looks like you have your wiring wrong

Its suppose to be :

So you would have had the opposite polarity for one of your phases, which would explain why the motor was vibrating. This could have led to your motors dying.

I seem to be having a similar problem, The print would not start.
After changing my seting to :
#define TEMP_RESIDENCY_TIME 1
#define TEMP_HYSTERESIS 50
#define TEMP_WINDOW 20
It still did not start, How ever I noticed I could get the print to start by repetitively pausing the print.! All of a sudden the print would start.
but alas It would only get about 100mm of printing (seems

What you are describing sounds like u have the following set to true in the firmware (Configuration.h):
#define min_software_endstops true
//If true, axis won't move to coordinates less than HOME_POS. So your printer wont home if it thinks its already at 0,0,0
Setting it to false should fix your problem.

I would like to hear about what software that people are using to create gear models from scratch.
I plan on Printing a 90 degree Hypoid Bevel Gear similar to a Differential gear system that I can connect to another mesh model that I have premade. Because it’s getting printed it’s important to have the gear accurately meshing together.
So far I have tried building the gear in blender with the

The point I was getting at is that you would not have to do any calculations to calibrate x,y,z.

I have already swapped over to metal bead chain for my Y and Z axis, but i'm thinking of changing that again to chain driven. I have a heavy tiled build plate on my Mondo which is one of the largest of the RepRaps :/.

Nice one Madkite. You have halved the gear ratio on your stepper motors. I am currently designing a gear box to lower the ratio of my X and Y motors to see if I get more accurate prints. I mite adopt your idea as well and have even more accuracy ! I'm hoping to get them as accurate as my Z axis @.@ ....... he he well see.

How about a multi headed extruding tip that can feed 3 different colored filaments(blue,green,red) through the same hole at once ?
Tricky to build I know, but you could have each filaments extruding at alternate speeds to create different colors.
I guess it would also be a huge task to change all the software to run it also.
Ignore this post if to far fetched >.>

How about having a circuit running through the tip or metal bed so that when you home Z and the tip touches the bed it stops at 0.0 ?
Thats the only way I can imagine u would get rid of the Z end stop. You would want your firmware to have a very good reaction time though or I'd imagine it would cause alot of problems.

I had an Idea of simply using 2x end stops at the ends of each axis.
The Printer could then run its own calibration by simply driving from one end stop to the other for each axis. All it would need to know is how far(in mm) each end stop is away from each other (which can be measured easily enough with calipers).
If the printer knows how far its moved then the software could then work out the

Just found this old post and though I would drop the answer here in case some one else had the same problem.
Wow is there any one that got the techzone monotonics that did not destroy their first hot end ?

Thanks morrist & Lambert.
Turns out you where right about the cable. I had used a long stranded Ethernet cable to plug into the tip manager. The original cable was to short to reach the extruder when the X axis was all the way to the right. To make it worse I had rolled up the excess cable and cable tied it together !! I had no idea Network cable could produce feed back or electrical noise.

Tip Problems:
After first hooking everything up and running repprapper software, the temperature or (Nozzle Current) read around 20 -25 normal room temperature. When I clicked heat on the Temp would jump up to 32767 then bounce around from what appeared to be the right temp and then back to 32767. Sometimes a completely random number would pop up usually around 2000 – 10,000, but mostly it wou

@DeuxVis: Thanks mate ill have a play with the firmware next time I get a chance !
@ owism8 To summarize everything above and fix your Z axis from skipping steps in SF with out changing the firmware, do the following:
1) Download the latest Skeinforge(43, Others versions probably still work with the patch but I would suggest getting the latest to be sure.)
2) Download DeltaFlight's "gcode_sm

Woot success at last !
I downloaded the latest Skeinforge 43, put in the new patch, checked the "export" was clicked and Wahlah 3D prints !!
Thanks guys
I still how ever would like to try to enable the Z stepper and run it with out the patch just to see if that works. But when it comes to the firmware I'm still stabbing in the dark with a crooked stick. So far I've downloaded arduino-0022,

I bought some PLA(5kg) from this guy.
I'm fairly new but I think the quality's pretty good. I got 3mm with a variation of about +- 0.2mm
(e.g. 2.80mm - 3mm) but most of the time its very close to 3mm.
Took quite a while to get to me though I was sent 3 different Tracking numbers before it was finally sent, arriving over 3 weeks later.
I don't know what the ABS is like ill try that next

I've just built the TeckZone Mondo with monolithics electronics. and have run into the same Z skipping problem.
I downloaded the patch strait from the original Denis patch.
I Tried the patch but it didn't make any difference to the G-code ?
What have I missed ?
Also I read some where that with the FiveD_G-Code Firmware, the Z axis stepper motor Is disabled until a step is needed to be made.

Blender Is very powerful tool once u get use to it.
I agree with JK, I have got both 2.56a and 2.49b and I use them both. 2.56a was Big change for blender and was kind of like a (window xp - vista upgrade). Alot of ppl went back to XP cause vista was crap :/.... same can be said for Blender 2.56a. It looks Flash and fancy but blender users are going back to 2.49b or still using 2.49b. Even some

Hi guys
I'm from Perth as well. Just had the TeckZone Mondo kit arrive in the mail.
It sounds like the mondo is not really for reprap newbies so this will be interesting to see how well I put it together with out any documentation.
Would be great to network with other reprappers !!
