I have an Ox-Build CNC router with a Tinyg and ChiliPeppr. My Y axis Jogs and homes OK. I can't Jog my X or Z axis, I have checked the continuity and pairing OK, 1ma = 2 (z axis) 4ma = 0 (x axis). I have tinyg connection to com3 and as I have said Y axis acts normal. This is my first CNC build, so consider me a noob. I just can't figure out whats wrong, any suggestions?
Steppers don't jog

Since you mention com3, Windows assumed.
SPJS running on windows as well?
A helpful first step would be to create a $$ parameter dump in the Serial console, copy and paste results into a text file, post the text file to a cloud drive (Gdrive, Dropbox, etc) and post a link (URL) to it here.
Here is a link to the parameters that I have right now I have not fine tuned anything since I can't get X & Z to move. I currently have X & Z min switch off while I am homing Y. https://www.dropbox.com/s/6ipc2pwtu57jopg/TinyG%20parameters%20in%20Chillippr.docx?dl=0
For now set $sl=0 until everything up and running
Looks like you have GT3 belts?
Z axis, $1tr=8000.00 ??
X axis $4tr=60000.00 ??
suggest use $_pm=2 on all 4 motors
I think $1tr and $4tr are your biggest impediments to progress
By the way, most all example posted by Synthetos will be for machines wired X-Y-Yr-Z. You have your machine Z-Y-Yr-X.
It will work that way, but your will always have to be mindful when reading example parameter sets, etc.
I have implemented you suggestions and I now have functioning XYZ axis, needless to say i feel a little stupid, I don't know how I missed 60,000 instead of 60.0. Thank You so much for your help. I will now go on to set-up homing and limits, and hopefully pay better attention.
There are a LOT of numbers to keep track of.
When you are satisfied with a setup, make a copy of the $$ dump and keep around for future comparison.
