Jan, the only way to set the maximum feed rate ($4) and seek rate($5) is to try various settings. Set these the same, and start low and go higher. $5 sets the velocity in a G0, $4 sets the maximum feed rate (F word) in G1, G2 and G3. In some cases people set the max feed rate to be lower than the seek rate, but I’d recommend keeping them the same for now to keep it simple.
The acceleration value $8 will also affect the feed rate and seek rate. In some high-speed cases $9 may also need adjustment, but only if you are having problems with cornering.

This is good news, but it’s also bad news – if the 2.2.17 driver is broken. How did you get 2.2.16? I had to hack the URL. Did you?
I will want to test this before changing the config page. I have 2 laptops that I use, an the one I’m on right now has the 2.2.17 driver in my “sources” directory, and I have no way to test what is actually loaded as it appears that the USB listing in the system profiler doesn’t show a driver unless it’s activated – which I will not be able to do for the next week due to travel.
In the mean time, happy cutting.
UPDATE: I had to run home. Here’s what’s in my system profiler under FT232R USB UART:
Product ID: 0x6001
Vendor ID: 0x0403 (Future Technology Devices International Limited)
Version: 6.00
Serial Number: A5014Y93
Speed: Up to 12 Mb/sec
Manufacturer: FTDI
Location ID: 0xfa122000 / 10
Current Available (mA): 500
Current Required (mA): 90
No indication of driver revision other then “Version” that doesn’t seem to correlate to the driver rev. How did you determine your driver revision?
Victor,
Thanks for registering at the forum. Your questions handled one-by-one:
– Here is a link about setting the pots. They are one turn pots so *please do not turn them more than 270 degrees* or they will break. However, I doubt the pot settings are your problem, so I wouldn’t mess with them right now. Just set them in the middle of the range.

– I’d like to confirm that you (1) have the kit from Inventables and that (2) your grblShield has the Z axis mod. Does your board have the little wire to the switch like the one in the last picture on this page? (scroll all the way down)
https://www.synthetos.com/wiki/index.php?title=Z_Axis_Mod_for_Shapeoko
– If it does not let me know. Can you please post your grbl settings? Z should not be more than 1200 ($3=1200), and might possibly need to be set to less, depending on the friction in your system.
– Check the Z axis motor plug. DOes this give good contact? If any 1 of the 4 wires does not contact or contacts intermittently then it could cause what you are seeing.
– If you swap motors – i.e. put the Z motor on Y and the Y motor on Z – what happens? This may be hard to do given that the motors are in the machine – you may need to remove the Y belt and/or change the grbl settings. Does Z work OK and Y have problems, or the other way around?
Please let me know how this goes.
I flashed a board with 338.11 and am ran it to completion, so it doesn’t look like that’s the problem, but can you please dump your TinyG settings with a $$ and post them?
D4 is the RX and D3 is the TX. I think both are working or you wouldn’t have any echo at all. The symptom you describe sounds like the XOFF is being sent by TinyG to the host and the host honors it, but the subsequent XON is either never sent or is not honored. If you look at the echo in Coolterm the periods (.) in the text are the XON or XOFF characters.
Separately, I don’t know why your Gcode has periods at the end of integer numbers, but this should not affect anything and indeed doesn’t give my setup any problem.
