Post your mpc so we can look at it. Are you using CarveWrights 1/8" bit?

[luckettg]

Yes, the short 1/8 bit that came with the CW set. I have not used it prior to this. I ran the X, Y, Z, and cut motor tests. They all homed and functioned correctly.

I did not see anything unusual with the mpc. Looks like you are using 3/8" material according to the carve region depth.

What quality setting did you select when up up loaded to the card?

Did you try running the project again?

[luckettg]

Yes, to your questions, and I may have figured out what is happening. The earlier question about the bit made me start thinking if my memory was right. It was not. The bit is longer than the 1/16 ball nose or the 3/16 ball nose. It came from Soigeneris, where I have been getting bits for a while. This 1/8 ball nose, #CM404-1250-100B, is a new type for me to try and I had forgotten about it. I am selecting the long 1/8 bit now and will give it another go and will report back. Every time I stop using my CW I have another learning curve to climb when getting back to it.

Ok, choosing the long 1/8th bit solved the homing problem. It homed correctly, then wanted me to load another 1/8th deep carving bit. I do not know enough about this newest deep carving feature, stopped it there, and am getting ready to go back to a 1/16 ball bit. Not much difference in carving time, both just under 2 hours. It will be a good test of the machine I guess.

[fwharris]

Yes with the new 2.xx version it is expecting the bit to be certain length +/- and will give the stall error if it is not.

[luckettg]

I am wrong again. My original 1/16 bit is the same length and fluting as the 1/8 ball nose. I have been using shorter 1/16 bits but that is in the shank, not the cutting area. With the bits I have been using, the CW overdrives the Z axis. It is definitely a problem with the software I think. The 3/16 ball nose that came from CW is a short one similar in length to the replacements I have been getting in the 1/16 ball nose carving bits. I am using a Rock Chuck with the 1/2 adapter, and have been using that for several years without any problems. This homing problem has shown up with the Designer 2.004 upgrade I did a couple of days ago.

A lot of people with the rock have fallen back to 1.xxx until the software lords can get the bit find problem corrected..

[luckettg]

Can I do that too? I shall give that a try. Thanks!

You should still be able to, when you installed 2.xxx it was not installed over 1.xx so if you did not remove it you should still have the program.
