Re: MKS Base v1.4 driver bypass - 6 years ago
The SPI pins are on the AUX3 header on the BASE, so that’s all fine. But the issue you have is that with integrated drivers, you’re going to struggle to get the EN, DTEP and DIR signals you need. I strongly suggest you just throw in the towel and get an MKS GEN instead. They’re £/$/€ 20 ish. Also, don’t be tempted by the slightly cheaper FYSETC Chinese TMC2130 drivers; they’re wired for standalby slippyr4 - General

Re: How to calibrate z=0 - 6 years ago
“Next I Home the z axis” What firmware? Do you have an end stop? In most firmwares, homing an axis equates to moving it to the endstop (that’s a known position) and then loading the value configured with M851 as the current Z. That completely overrides all you are doing with G92, which would not be saved to EEPROM anyway.by slippyr4 - General

Re: Heatbed can't keep up with extruder fan [thermal runaway] - 7 years ago
100k is nominal; (obviously) it varies with temperature so 85k is nothing to worry about. What is your bed resistance? (Remember to subtract your probe lead resistance (the value your meter shows when you short the probes together))by slippyr4 - General

Re: Auto-Tramming with different offsets for different materials/ - 7 years ago
You're looking for M851 which changes that exact value. But you could just use different first layer height settings in the material profiles of your slicer.by slippyr4 - General
Re: ramps 1.4 smoking when heating the bed - 7 years ago
Quotevfwfw I have been looking at that board and wondering if it was any better. Do the same A4988 stepper drivers fit the MKS board? The MKS GEN, yes - it takes "standard" polulu type plug in drivers. The BASE has integrated (not replacable) A4988s. I have used a gen on a 24V printer with a bed running about 220W so about 9A and it's fine; the printer I have with the MKS base has 12V and aboutby slippyr4 - Prusa i3 and variants
Re: ramps 1.4 smoking when heating the bed - 7 years ago
I'd personally not bother with ramps at all. The MKS GEN and MKS base are much better boards, with an extra mosfet you can use for another extruder or a fan and the bed mosfet ar capable of enough amps. They cost about the same as a budget ramps clone and budget arduino mega clone together. And are pin/firmware compatible with ramps.by slippyr4 - Prusa i3 and variants

Re: DIY kit recommendations? - 7 years ago
Quotesylviatrilling I am a bit reluctant to change the firmware as it will void the seller's warranty. but your printer is a dirt cheap model, and you started this thread talking about replacing it with a printer costing much, much more - so what do you have to lose flashing better firmware? very little.by slippyr4 - Prusa i3 and variants
Re: Prusa_i3 Heating and Fan - 7 years ago
QuoteKnedberg09 My fan has no ducts. Simple fane mounted to the face of the extruder motor. That therefore sounds like it's your extruder cooling fan and not a part cooling fan, which Roberts_Clif was discussing above. That fan is important and not optional; without it you'll get problems including frequent blocking of the extruder.

Re: Need help with new board - 7 years ago
The board is pin compatible with RAMPS 1.4 and 24v capable. They’re good boards. Geometry is a consideration when changing from makerbot/mightyboard to ramps/marlin. In the makerbot world the origin is the bed centre, but usually on marlin based printers the origin the the bed front left. It actually doesn’t really matter but your slicer and your firmware need to agree where the origin is, orby slippyr4 - General

Re: From 12V to 24V - 7 years ago
Quotejinx think if i was going 24V I use mks mosfet to control the bed, inpart to keep the heat off the main board. False logic; for a given power the current is lower at 24v so the heating in the MOSFET is lower.by slippyr4 - General

Re: Any experience with this hotend? - 7 years ago
QuoteDjDemonD Another question on this topic, the e3d cyclops 2in1out with 1 nozzle is described as switching not mixing, so is the junction between the two filament paths in the heatbreak or heater block? If it's in the heater block why isn't this considered a mixing hotend? I’ve wondered that myself. The mixer is in the block, and, in their engineering drawings ( ) they call it a “mix block”.by slippyr4 - General
Re: Is this too much for a A4988 Stepper driver? - 7 years ago

Re: Help a noob replace a motherboard - 7 years ago
Headers are the connector bodies. Your printer uses 4 pin ones (of type JST-XH) and the new board needs 3 pin ones. You can leave the green wire disconnected and you will be able to remove the pins from the existing header and pop them into a new one. You can see what I did on the photo I posted earlier (which is of my mks gen board installed in my replicator clone printer) One of the many generby slippyr4 - General
