Alden, I’m using Mac Coolterm. I’m not sure about line numbering in Partkam, although it’s a short enough file where I could hand-code them.

I agree on short-cycling… Let’s try to tele-meet over the weekend. I’ll be working the rest of today, tomorrow and Sunday from 11am Pacific til late-at-night Pacific. Maybe we can do a g+ hangout?

OK, I’m much closer today but things are still not quite right. Here’s the gist:

-I found that the chips were getting pretty hot, so I added a heatsink and fan.

-I adjusted the current pot (there’s only one on my board) per Riley’s suggestion, and that did seem to fix the stuttering. The green axis light will sometimes stay lit on X and Y, but it no longer flashes.

-I enabled power management on the Z axis since it is on a leadscrew, and there is no indicator light after finishing a Z command.

-I can send Gcode to the board, but I’m consistently missing steps on the X and Y axes.

I think either my JM settings in the firmware are still off or I have not actually set the current correctly. So my questions are:

-Is there a clear indicator of what the current pot is set to, and which turning direction increases current? I just tried randomly dialing it up and down today to see what happened, and tweaked it until the stuttering was no longer happening.

-What is a reasonable Max Jerk setting for a machine configured in inches? I reference the wiki in originally setting mine to 2,000,000 in/min^3, but Alden mentioned that this is too high.

Here’s my updated config settings:

Alden, here is the version info that I got thru CoolTerm:

#### TinyG build 322.02 – “Filariasis” ####

alden, thanks, I’ve got an mkII, but for some reason I’m having trouble flashing the board. I can connect to the programmer via avrdude when it’s attached to an arduino, but when I try to connect to TinyG, I get this error message:

root@lilcnc-desktop:# avrdude -c avrispmkii -p x256a3 -P usb

avrdude: stk500v2_command(): error in CMD_XPROG_SETMODE: Unknown
avrdude: stk600_xprog_program_enable(): CMD_XPROG_SETMODE(XPRG_MODE_PDI) failed
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude: stk500v2_command(): error in CMD_XPROG: Unknown
avrdude: stk600_xprog_program_disable(): XPRG_CMD_LEAVE_PROGMODE failed

avrdude done. Thank you.

This is consistent on Windows 7 & Ubuntu Linux.

I’ve done some investigating online, and it sounds like I may need to update the mkII’s firmware via AVRstudio? Trouble is, I installed the libusb drivers on Windows, and it seems like they’re interfering with AVRstudio as it can’t connect to the board.

I’ll try again tomorrow on a different machine. Thanks!
