Interesting, though I still believe it is a problem host side.
A search of the file says that it is the nVidia OpenGL interface driver, which I had up to date months ago, and pointless to update as there are no new changes for my video card, 8800GTS 512.
I have also played with recently a game called RoboForge, which runs under Java and OpenGL, and had no problems I could see.

RepRap Host
I have to say thanks to all who responded, and other threads that I just found today, whcih cleared up a lot of old outstanding problems I had with the host and firmware.
Just got one more.
Typical error message

I think I have mine working now, I reinstalled the files for the firmware over, leaving the config intact.
Then I deleted the applet directory, and recompiled, the error did not come up, so I went on to uload it to the motherboard.
Then of course, I ran the host first before turning on the machine, as I have always done, as this was the work around to the host always crashing at odd times.

With the debug turned on, attemting to jog the Z axis by 10mm.

This issue isn't to do with slice and dice, just to simply jog an axis, which is just simple commands to the hardware.
Clicking on a button to move an axis causes the host to crash and freeze. Meaning a full system restart to free up the comms again.
Your problem and mine are probably related.
Forgot to mention that I also reduced the baud to 9600, this cleared up a lot of comms problems befor

I would like to know if anyone else is having problems with the latest release on sourceforge.
I'm using gen3 electronics, which are known to be working with a release version last year.
Just decided to try out the new host and firmware, ensuring the same firmware settings I use for my printer have been migrated properly.

I am, having the same issue, after trying out the latest released 20100806.
I've reduced the baud rate down to 9600, and cleared up a compile error bug under the intercom.h file, where "Serial1" wasn't declared, fixed that to "Serial"
Would like to hear of any ideas of what may be happening please?
I am using Gen3 electronics, with no heated bed, and using the Classic Mendel variables.

Short question, is there any support on the board for thermocouples?
I can't tell in the photos if you do or don't, and this is a pretty important feature, if just for the extruder. Also, I will never use a thermistor for measuring the hearter barrel, unless it has a high temmperature rating and easily obtainable, which K type thermocouples are.

I am using drawer slides, the ones without a ball cage. If you get your dimensions correct, there is NO lateral play. It surprised even me, thus requiring only 1 bearing to reduce the axial Z rotation.
I have seen videos of people using ball cage versions of these slides, and they are even better.

I've done a sketch of the new design, and currently waiting on feedback from a mate, or anyone else.
And made a mockup in about a half hour or so
A suggestion came from someone that maybe having a spring underneath would be useful to keep the contact between rail and bearing consistant, I am still unsure about this.
The mockup works ok, though a shim would be need to prevent interference f

I'm looking for ideas to replace the current Y axis gantry (flatbed A4 scanner) on my robot, with something more constrained on both sides, that I can make quickly and easily as well.
I've uploaded a sketch of a possible method using liner spline bearings, however I am finding it difficult to find cost effective bearing solutions. The idea was submitted by a mate of mine, using spline bearings

I don't think my cartesian robot is quite ready for such an honour as being on the wiki.
It WAS suppose to be finished by Christmas, last year, lol.
Typical problem is designing the extruder, from junk lying around, becoming more and more machined (I ask a friend to make the occasional part for me on his work mill/lathe.

Just posting some info in case someone asks, I fitted the incomplete Z axis to my Y axis gantry, held up with just a regular flatbed scanner. Initial tests were confirmed when I asked an engineering friend of mine of how to stop the gantry twisting.
The solution we came up with is.
Build it from scratch, but use the drive train and bearing bushings, make a new gantry which may even need a se

NZ miniature bearings for RepRap + Wade extruder
NZ$82
VXB same basic kit
US$40 + 13.15 shipping = US$53.15
Current currency exchange rate 0.7531
Total = NZ$70.5736 including shipping

Like wade said, check to see if there is any AC on the DC.
I use a DC benchtop power supply at work, and was always getting AC zaps on my skin, fixed that by tying the gnd of the supply to earth.

Tried calling Saeco bearings, or Auckland Bearings?
Someone else you could ask, and i'll ask tonight when I meet up with him, is Tim from MindKits.
Else I see that VXB in the USA are very cheap, even if you take into account shipping.
Normally these (called micro bearings in the industry) are very expensive, and for the quantity in a RepRap that is a lot of money.

That is ceramic grease, PTFE grease may react with some plastics.
I've got access to MagnaLube (PTFE grease) at work, so I might do a reaction test with PLA to see how much the two react.
