Put the Z endstop at the bottom, use this design:http://www.thingiverse.com/thing:394903Make it a MIN endstop in your Marlin configuration and makesure it's on the MIN pins on the RAMPs board
Thanks, I am working on an updated version of the Instructable using the "rework" design and a Hexagon 1.75 nozzle.Cost was approx $600 Canadian. More than the cheap China kits, but the quality way better.
You should be fine, just use the Instructable as a guide. email me with any questionsSteve
Normal. The 6-32 nuts are "chunky" or have a large face, so there is plenty of contact with the t-slot. I am doing a new Instructable on my latest build which has improvements on the z-axis end stop (and adjustment), nut holders for the bed leveling and a 1.75mm filament extruder and hot-end
No difference really - my new build is using 350mm and they should be just fine
pretty sure it's something to do with the thermistor, check your Marlin for the correct thermistor type and also check the thermistor connection to the RAMPs board. Measure the resistance of the thermistor to make sure it's not shorted.
Do you get it working up to Step 3? Wiring up the sensor and reading the temp on the Arduino serial port?
The bridging between a POTS line and VoIP line is what make the ObiHai 110 and above different from the usual ATA adapters.
with the suggested 1.8 degree stepper motor you need 200 steps to do a rotation. With 3.75 degree stepper motors you need 96 steps to do a rotation, so while technically it could work you would have less than 1/2 the resolution of a 1.8 degree stepper. Why not use what is suggested in the Instructable?
Hi, I never did a complete BOM for the nuts and bolts - mainly because there isn't enough time in the day to look at every bolt on the printer and figure out if it's an 18, 20 or 22 etc. Rather we bought an assorted size of M3 bolts in 50 packs, so I would say M3x22 will be fine and if you find you need something longer then try a mom & pop store. For example locally in Vancouver, Canada we have Pacific Fasteners, Canadian Stainless Fasteners etc all smaller fastener specialty stores that stock metric fasteners. Hope this helps

I usually change the MOSFET with a IRLB8743PBFI also bought myself one of these RAMPS https://www.tindie.com/products/staticboards/ramps-14-sb-premium/https://www.tindie.com/products/staticboards/ramps...
Are you doing a Y "home" in pronterface first and tripping the ends stop switch? Are your end stops working. The printer needs to know the start point (home) before it will move the full 200mm in the opposite direction.
