I can move it up however far I want, to let's say x+15mm. Z-endstop switch is monitored when moving Z axis down via LCD menu or G0. X and Y homes fine but Z all of a sudden moves upwards instead of down towards the endstop/buildplate. M119 shows all endstops open. The BLTouch probe should deploy and the Z axis should move down. i just have trouble make the Z axis and/or the gcode with slic3r be the correct one, x, y, and e, seems to work fine, but Z keeps struck at the Z home position, on the gcode it only move .325 on the firs Z position, i dont get to Z In Marlin I had to set the #define DEFAULT_AXIS_STEPS_PER_UNIT for the z axis to 1600 to get the z axis to move 10 mm when commanded to move 10 mm.. What would be the pros and cons of going to half or full steps and The Z axis should move down by the Z offset we set above. // Specify here all the endstop connectors that are connected to any endstop or probe. The patch i meant only … When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it takes 1 minute to hit the endstop again. You have to go into Prepare-Move Axis-X,Y or Z Axis, .1, 1 or 10mm then you can move one axis at a time. Check the fit of the paper - if it is good, and the nozzle seems to be at the correct height, then we are done with the calibration. X any Y work fine, both Z motors move down just fine, when homed. Once you have edited it, we are going to indicate to our dear Marlin that our 3D printer has a limit switch (sensor) on the Z axis. If the gauge is loose then you need to lengthen the travel on this axis- you are working on … Unfortunately i noticed, that during print the Z-axis wont move upwoards when a new layer begins and it should move upwoards. Save current position and move to filament change position. To set the Z axis home offset on the 3d printer, you will use g-code commands including M206 for the home offset, M500 and M501 for the Marlin Firmware EEPROM feature, and G1 for controlled move to Z axis zero position. Min software stops are currently disabled, as I try to set the printer up. I inverted the Z-axis in the firmware (by setting the value to true instead of false), and it did the same thing, but the other way around - it would only go down. G1 Z2.0 F3000 ;Move Z Axis up G1 X232 Y20 Z0.28 F5000.0 ;Move to start position G1 X232 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X232 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X232 Y20 Z0.28 F1500.0 E30 I have to cancel everything. My machine has a zero point which is not over the build platform, so to get the nozzle over the platform I have to move the x and y axis. … I just finished assembly of Anet A8 (Prusa i3 clone). Ditto for X-home but not motor disable. I went to a parallel configuration. I just finished a scratch build printer (cartesian) and everything works fine except the x axis is crooked when the dual Z motors move the axis up and down. When the Z axis is secured with smooth rods, along with threaded rods which have bearings on one end that move it up and down, you won’t have this problem. I tried swapping the pins for the clip and the plate. Still goes down to the same value as M851 Copy link Contributor Blue-Marlin commented May 19, 2016 • edited by thinkyhead Hmm ja. I have been able to draw some forms to check if it’s square. Examples: I turn on the printer, and say the extruder head is at distance x from the bed. My X and Y axis both work when sending commands to move in the positive and negative direction, but my Z axis only moves up. The machine will then move a further -0.7mm in Z to This feature is usually disabled by default in Marlin but can be enabled when recompiling the firmware. Touch the end of the probe with your finger to trigger the end-stop, the following As soon Right now I am using the LCD screen to home the machine then move to my material origin so I can set the offsets. Using The main thing here is to write down wheter an axis is moving the right direction or not. Today I installed stepper dampers for X and Y. Replugged the wires and presses autohome. Tried to implement latest Marlin on my reprappro with ramps 1.4. prusa-i3 marlin electronics z-axis firmware I had an idea the other day and I want share it with you guys and ask if you think it would be worth pursuing. Navigate back to the z axis movement and increase the z axis by rotating the knob clockwise to about 2.0 representing 2mm.

If it looks a long way above, click the Z move 1 button, then go down by 0.1 until you reach z= 0. Prepare > Move axis > Move 0.1mm > Move Z Slowly move the Z axis down until you have the correct first layer gap (paper or thin card method) Note the distance on the display e.g. I have full manual control of all axis... moving up/down/homing ect, all with manual control. No problems there. If combined with a Z and P field (example: G31 P312 Z0.7) this will set the Z height to 0.7mm when the Z-probe value reaches 312 when a G28 Z0 (zero Z axis) command is sent. Write any script, and while the gantry is up high, pull Z-Axis Move Planning in Practice And that is the big limiting factor with Z-moves: the distances are very small. Hello, I am having an issue where I click z home and it goes down a few millimeter and stops. Many 3D printers will use the combination of a threaded rod connected to your Z stepper motor shafts to … Hi, I am new in CNC but have few years experience in 3D printing. nothing I do seems to change this. This tends to be from insufficient current. i use Marlin (from this site) on a ramps1.4 with dual endstops X and Y. I have 2 questions regarding endstops. G'day, I have a new Ord Hadron and having an issue with the Z axis. Just to clarify I didnt add in anything extra besides changing the settings to speed that worked in my previous version. A move of just 0.1 or 0.2mm doesn’t give much time or space to accelerate and slow down again.
