Don't get caught up paying double price on amazon!
If you read any posts on the forum you get the idea that we like to fix and build. Our 3d printing experience has us singing the prases of the longer lk1, basically the ender 10s with various feeders and hot ends. We can get into some heavy production runs and make some really incredible stuff but it's time to explore something different. Our current setup is using the Duet2 wife as our controller and the duet web control as the os so we will stick with that except we are moving to a duet3 with raspberry pi setup.
Part 1:
First step gathering parts.
I failed to mention our goal is to source the most inexpensive components (china) that
is the mechanical stuff. Of course selecting the duet3 will kill any budget, but we are willing to pay extra for top interface and production. If its over kill we will change it out.
The Frame purchase price was heavy discounted but the quality and specs are good
The Drive parts about 20% discounted, again this is not amazon shipping it's china mail.
Hardware kit 20% less
Rails at least 20-30 % less
The Bed was an odd selection, it is 220v but i got it off amazon for 80 delivered, this part has 90 dollar shipping fee even from eBay, so its around 170 bucks, I had a 110v to 220v upconverter but if you purchased this it would add 35 bucks so i'll call it 115price
Still lots of parts to go but I have enough to start assembly
Going to create a tools catagory and tool usage to explain the terminal end builds on the Duet3 controller
I was trying to explain how to quickly recover from moving the gantry assembly. Like from a head crash or just tugging on it and realized what i was doing was just taking to long. I had to make a couple belt adjustments, it had been a month sense i used this unit but was still getting variable results so this is the solution.
Cabinet trim board layed on the bed long enough to lay the gantry on it on both sides, do this twice and the machine will pass the true bed leveling command
Bed leveling is automatic if you can get the bed withing 1mm.
My initial step is to have a consonant measure stick and hit each corner. I use a molding with clean surface
I command movement to the corner then release the motor and make a manual adjustment, jog down with minor steps
1 First enable control of the head assembly
m564 S0 H0 allow steppers to move without homing, move the head to the first corner, jog down the head till it contacts the measure device.
then zero the Z for initial setting
G92 Z0
Lift the head 5 and proceed to the next corner
Mine is about 5mm high, at this point release the motor (M84) and manually lower the head till it contacts the measure stick
The result should be touching the measure point and z0
Zup 5 and motor to the next corner
You get a process and it becomes pretty simple EXCEPT if you don't pay close attention you will drive the unit where it doesn't want to go!
m84 release motors
M302 P1 to allow cold extrusion.
M84 disable steppers
M84 turns off idle hold and this can also be applied to specific motors e.g. M84 E0:1:2
